Prime95 26.2 and 26.6 "Hang"
 
My son allows Prime95 version 26.2 to run 24/7 on his desktop (because he loves me & because I gave him the PC). As far as I can tell from results.txt, it has been running reliably for years. However, I am house sitting for him this week and have noticed on several occasions that the Prime95 window would not open when I double clicked the green icon at the bottom right hand side of the window. Mousing over this icon shows causes a status window to appear, but Task Manager shows System Idle at 9x% and Prime95 using 0 cpu time. The only way to get Prime95 running again is to reboot the PC. Stopping it with Task Manager and trying to restart it does not appear to work. I downloaded version 26.6 which exhibited the same behavior except for appearing to "hang" sooner. Results.txt, Prime.log, and the Windows XP Event Viewer Application Log show nothing unusual.

Is there a parameter I can add to Prime.txt or Local.txt to generate more detailed debug information/error messages?

I can't help with debugging, but for variety (as if you need more work :smile:) you can try 27.7 and see if that's any different from 26.6 (I doubt it, but hey, one never knows :razz:).

Did you play with hiding/unhiding the tray icon?

Try launching p95 second time. This should normally bring up the program's interface (reopen the same instance already running) and you can see what the problem is. Seldom this will not work, the new launch will open a new p95 instance. If you see two copies in task manager, and nothing is happening, then something is bad there, you can try to rename the prime.txt and local.txt and start a clean copy.

Some time ago I used to hide the tray icon (make the p95 "invisible" for normal user, from "options/no icon") when p95 was running in my daughter's laptop, so she could not become curious and close it. Once invisible, you have to start the program second time (on top of the first) to open the workers/windows. In some cases this was working, i.e. just opening the interface of the current running instance, where I could change the parameters. In some other cases it did not work: it just launched a second copy of p95 (and I could see two of them in task manager). In this case, I had to go to options, select "tray icon", close (exit) the running copy, kill the copy which has no interface with task manager, restart.

This usually solved the problem, i.e. after restart I had the tray icon and I could operate it normally. Usually. Sometime, very seldom, after this combination of operations I was ending up with the icon, but NOT functional (exactly as in your situation). After few more trials it usually re-open the right instance. This assuming you have no strange settings in prime.txt/local.txt, in such case you will need a fresh restart.

LaurV,
No, the tray icon remains visible all the time and even provides a "pop up" when you mouse over it. That is how I noticed this odd behavior in the first place. Because double clicking the tray icon multiple times did nothing, I opened Task Manager and discovered that the PC was really idling. Note, this is much different than a PC "hang" where nothing works.

LaurV 2012-05-17 14:52
Well, the whole idea of my post was to launch a NEW copy of prime95 from the same folder. This [U]may[/U] bring up the interface, and you [U]maybe can[/U] see what's going on and why is paused. Some errors or some settings in the config files, like "NoMoreWork=1" (stupid example) could be the reason, but unles you see the interface, you don't know.

Alternative is to post your logs and config files.

[I]Prime95 just froze right in front of my eyes.[/I] I had opened the Prime95 window, changed the Worker Window work type from first time test to trial factoring, and saw the change communicated to the Prime95 server in the communication window when the freeze occurred. Here are the symptoms:
1. Task Manager says Prime95 is using 0% CPU;
2. The open Prime95 window does not update or move on the monitor screen;
3. Double or right clicking the Task Icon at the bottom right does nothing;
4. Mousing over the Task Icon pops up a status window;
5. Double or single clicking the "Prime95 status item" on the Start line at the bottom left changes focus but does nothing else;
6. Right clicking this "Prime95 status item" pops up a dialog box with everything grayed out except Minimize and Close. Minimize does nothing. Close pops up Microsoft's "End Now or cancel" dialog box. Selecting End Now works normally and Prime95 eventually disappears (e.g Task Manager Process and Task Icon vanish);
7. Restarting Prime95 adds it back to Task Manager's Processes list but it does not [U]actually[/U] start or use any CPU. The Task Icon pop up box now says "not running". The System Idle Process still uses 9x% of CPU;
8. Results.txt has not been updated since 04/23/12;
9. Prime.log was originally updated on 05/18/12 at 09:08 when Prime95 froze;
10. Prime.log was also updated on 05/18/12 at at 10:17 when I "restarted" Prime95;
11. Prime.log contains the following text:

12. Prime.spl was updated on 05/18/12 at 09:08 and at 10:17;
13. The Event Viewer Application log shows nothing. The System log only shows the unexpected Prime95 termination in step 6.
14. From previous experience, I know that I will have to reboot this PC in order to [I]actually[/I] restart Prime95 and have it do any useful work;
15. In [B]all[/B] other aspects, this PC is acting normally;

Any ideas guys? I am at loss on how to proceed.

In the primenet section of prime.txt, add the line Debug=2

Restart and post the relevant prime.log entry. It looks like communication with the server is hanging. You might try version 27.7, but I don't remember if any bugs have been fixed that would address your situation.

RMAC9.5 2012-05-19 04:41
Thank you George for your reply.
Debug=2 was already part of Prime.txt when I checked it just now. Is it a "standard" part of the default version of Prime.txt as I do not remember adding it in the past? Here is a copy and paste of the [PrimeNet] section.

"[PrimeNet]

Here is a copy and paste of the most recent Prime.log text.

Note, the only change I have made to this PC (except for antivirus updates) since I noticed this Prime95 problem is to download (at 11:54 today) and run the dotnetfix.exe from Microsoft's web site. This was done because the security update for Microsoft .NET Framework 1.1 SP1 has failed to install multiple times and a Google search suggest that the above exe might be a fix for what I believe are two Windows XP related shutdown issues. So far so good today, Prime95 has run normally!

Please use [code] tags, e.g. "Code: [noparse][code]This is code[/code][/noparse]" will produce this: "Code: [code]This is code[/code]"

You can also do [quote]; they do the same thing, except that for large data sets [code] will limit the size and add a scrollbar, whereas [quote] will use as much space as without the tags.

Shorter already :smile:

(Nothing looks wrong from the output, but of course I have almost no idea about Prime95, especially not the comm code. :razz:)

Debug=2 is not standard.

Your log file looks completely normal. If this output was produced just prior to your "hang" then I'd say the comm code was not at fault. We probably have a mystery here that we won't be able to solve.

Prime95 26.2 still Hanging
 
I checked my son's PC yesterday and this afternoon. It is still causing Prime95 to "stop processing" when Prime95 [U]unsuccessfully[/U] communicates with the server. The "Prime95 hang" continues until the PC is rebooted. Here is [U]approximately[/U] one week's worth of Prime.log text with most of the "successful communications text deleted" to fit within the 10,000 character limitation. PC rebooted 05/20 morning & 05/25 evening = 4 days of work lost. Can Prime95 be modified to continue processing while waiting for a server response?

George, any ideas on changing Prime95 to continue processing while waiting for a server response?

Dubslow 2012-05-25 22:59
It [i]should[/i] and normally does not depend on actually getting a response. This morning, in fact, I got a timeout on a result but Prime95 continued to work fine. More specifically, I did get an error message. Furthermore, the comm thread is separate from the worker threads, so even if the comm thread runs into an unhandled error, work should still continue...

Perhaps it's a bug in an older CURL version that has since been fixed?

[strike]Does this happen with 26.6?[/strike] Yes, apparently. Hmm.

More Clues which May or May not be Applicable
 
On restart this PC gets message about .NET-BroadcastEventWindow.1.0.5 ... needing to be manually stopped. During the most recent restart, I clicked Cancel on the End Program Windows popup window for this item and canceled the PC restart. Canceling the PC restart caused Prime96 to "freeze up" again. Stopping the Prime95.exe using Task Manager and then starting it again by double clicking the Prime95.exe restarted it in its "frozen" state (i.e. Task Manager shows it using 0 CPU and 76K of memory). The Event Viewer doesn't display any thing of interest for this "freeze up" time.

Logging off to restart this PC for real.

The log file isn't informative. Basically it shows that prime95 called the CURL library which called Windows and the OS decided to hang prime95. I'm afraid networking internals are outside my area of expertise.

The prime95 workers are in separate threads, so in theory the workers shouldn't stall. I don't think 27.7 will behave any differently as it is linked with the same cURL library.

Unfortunately, you seem to be alone in having this problem. There must be something unusual about your Windows install.

I'm afraid the only things I can think of to try are 1) building your own prime95 with the latest CURL library. Maybe the cURL people fixed your problem. And 2) you can try putting UseCURL=0 in the [primenet] section of prime.txt. This is described in undoc.txt and should use some really old sockets based comm code. It hasn't been tested in years.
