Weird. My rtorrent client still isn't seeing any seeders, yet can download CentOS images just fine.

What trackers are you getting updates from?

These are two trackers that I got announcements from in the last 30 min:
udp://tracker.opentrackr.org:1337/announce
udp://tracker.open-internet.nl:6969/announce

I agree. Let's not forget what happened to Seventeen or Bust.

I don't spend my days immersed with server and VM issues, but I would have thought that a created minor VM would be only utilising a nominated CPU core of the vast number of available CPU cores within the server metal, and prescribed disk and memory and network resources.
So I was unclear about why occasional mersenne.org busy behavior would be significant.
I guess that disk storage contention could be a greater issue for debate, but then perhaps even that is perhaps largely negligible for comment with the huge number of spinners that Aaron has likely incorporated.

If anyone is using the methods posted here to mirror Mersenne.ca's database, especially for the 1G to 10G range which is beyond Primenet's range, please take the time to purge this composite factor from your mirror:

Composite factor of M3,321,930,431 is 2118762583699087568351 = 6643860863 * 318905321377

This composite factor somehow made it (back?) into the Mersenne.ca database even though James himself posted about it back in 2012, which makes me suspect that it was somehow added back in, in some update from some other source at some point.

Note: this is the only composite factor in the Mersenne.ca database.

Possibly by the time you read this, James may have already removed it.

I have no idea how or when it got back in. I have re-removed it.

It is known. I'm working on it. Should be fixed in an hour or two.

edit: finished updating.

[alpertron]

I found that in page https://www.mersenne.ca/exponent/2535283 , the fifth "prime" factor is the product of the third and fourth.

More room

Thx

Indeed. I thought I had found and fixed the codepath that was letting composite factors sneak in... but apparently something's still not quite right
I'll have to have another review of how these composite factors keep sneaking into the data. Thanks for letting me know.

edit: I've found and squished another typo that was (occasionally) letting composites through. I hope that's the last of the bugs and no more composites sneak in. Let me know if you can prove me wrong.
