Other Factordb Problems

[chris2be8]

I've sent Markus an email asking him to look at them.

Markus replied, he's set those 3 prime. And searched the whole database and found 9 others.

Thank you both!

And I asked him to look at:
1100000001598147064 ((2^692-1)*692##+1)/1286083057971077
1100000000781996714 (776*776##+1)/92857
1100000003810407374 (778*778##-1)/31021540273
1100000000953365184 ((2^722-1)*722##+1)/35099
1100000001399909747 1350##/675##+675##

He replied that there was a bug in the code, '##' gets passed to pfgw directly which interprets it differently to factordb. He said he would fix it and re-queue potentially false PRPs and false composites for re-processing.

So we should not see any more bad PRPs (fingers crossed).

And I sent my thanks for fixing this long standing issue.

Excellent! Thanks for working with Markus on these.

Why isn't Wget working with FactorDB? I tried to update a sequence (41299062275692180), adding 45 terms, but it's not working:

Usually it goes through all the way, and adds the resulting terms. The DB seems somewhat responsive in my browser, but it's now saying that I've exceeded my maximum number of parallel processing requests.

Also, I think it's ridiculous that we can't access the limits page when we reach the parallel processing limit. Also, I've noticed that the help pages seem to have disappeared.

UPDATE: Now it says that I've reached my 2400-second CPU limit. Why did it eat up all my quota like that?

Static pages (like the list of limits that used to exist) and a user's limits page should be exempt from the limits themselves, so that a user knows where they stand. I'll email Markus about this.

I had 3 occasions yesterday when factordb had problems. They started when attempts to post a factor timed out, then after 4 such I got "You have reached the maximum of 4 parallel processing requests.", then after a while "You have reached your hourly limit of 2400 seconds CPU-time." After an hour things started to work again.

I suspect the attempted posts were looping, so once my script had tried to post 4 numbers I hit the first limit, then after they had used 2400 secs CPU I hit the second limit. They probably got terminated then so I could continue once the limit had cleared.

But I can't tell why they looped.

I have had this scenario occur several times over the last few months, but never determined why.

Markus responded to my email today. He has added additional connection slots for the status and limit pages, and he also added the current limits to the limits page. The changes are already live.

Thanks Alexander, for helping bring this about, and to Markus for all the work he puts in.
