Server outrages - Page 33

gd_barnes · 2014-08-05, 20:50

Just to make sure everything is OK and for my own comfort level, I just now shut down the server machine for a couple of minutes and then restarted it. I then restarted all of the servers "on screen" so that I could see them running. I didn't feel comfortable not being able to see what was running.

There have been no pairs in LLRnet port 12050 for a long time. I did not start it.

For future reference, here are the ports that are currently running:
PRPnet:
1400 (CRUS)
1465 (private)
1468 (NPLB)
1470 (private)
2000 (NPLB)
9000 (NPLB)
12000 (TPS)
13000 (TPS)

LLRnet:
3500 (NPLB)

Thanks Gary.
I'll cast another incantation so they automajically start on your (real) screen after a reboot.
Running some tests for that here just now.
I'll let you know when done.

I have some big problems to reach stats page on NPLB and that started after the first outage when Gary was away.

It seems that there are some problem in DB or apache .

as I understand crus is on the same server and I have the same issue there.

Big problems on page with lots of data. Most times they time out.
Some time I get 20 -50% of the data.

50% of the time I get nothing just a white page and then it times out.

I think you need to optimize DB and check apachee, Mysql, PHP.

Just some guess

This is no critic just information :)

Good news for us - everything is fine. Page & DB response is very snappy.

Bad news for you is that either:
somewhere between you and the server is a "poisoned" cache.
edit - you can test this by over-riding your primary and secondary DNS server addresses and trying a different ISP's DNS server - edit
OR
you are having a problem with the Prime List page where there is a slight delay while your browser downloads 8000+ primes and then the javascript table client re-renders the list in a pretty looking table with pages. (The port status page however does not use that javascript plugin and should display very fast.) At a guess you may have a local issue with the javascript plug in. (I hope you are not using IE !?)
edit - no. you said you had the same problem on crus so this does not apply - edit.
OR
Maybe your browser is using the "hardware acceleration when available" which is a GPU/APU which is also crunching? That can result in broken page rendering also. A few recent versions of Chrome/ium have been bad at that.

It could be one of many reasons, but the good news is it is not a problem on the server or a response time issue - considering that I am on the other side of the world over 15 'hops' from the server. :)

Gary,

I will not script that auto-start tonight.
I could but it's not quite finessed.
It doesn't quite behave like a terminal window that you opened yourself.
As soon as you stop the program running in it, the terminal window closes, which is not how you would want it to behave.
I'll do some more tests after I have moved and overcome that behaviour.

PS - I did fiddle with your server. It should log you in after a reboot now.

ITMT - Welcome back :)

WHAT: There will be a planned outage of the NPLB DR server for relocation of the hardware. This outage will not affect any normal NPLB services.
WHEN: from 24:00hrs 2014-08-07 AEST .
DURATION: The planned relocation window is 5 days, target is 2 days. The shortest possible turnaround on the critical path is 24 hours, depending on network build tasks, lunar and astral alignments, the lucky number 16, the market price of Longjing in Zhejiang Province and whether the roaring forties happens to be blowing at the time.

NPLB DR server is back online.
It was a super-moon. There were no lucky numbers so the pool jackpotted. The price of tea in china didn't budge. The roaring forties were stuck at twenty. Even the westerlies turned up a week late.
That was 11 long and frustrating days.
But we are back in business.

Nice job Dave, as usual.

AMDave · 2014-08-27, 11:32

I have been getting connection failures to the NPLB server for about 1 hour, but the server contacted me successfully on schedule about 16 minutes ago.
The DNS and IP address is the same so I suspect an ISP / network issue is in progress.
Server is up, but the inter-webs is confuzzled.
Hopefully it's just a regional issue for me and not happening to you.

All fine this morning.

It does look to be down across the board now - all of my clients (at two different locations) have fallen back to PrimeGrid servers, and I can't reach any noprimeleftbehind.net services.

Dave, are you still getting pings from the server? If so, then this may be an IP/DNS issue (since that would mean the server still has internet access, but we can't reach it).
