Other Factordb Problems - Page 29

It probably has something to do with the workers section of the status page being broken. Syd probably had to take the whole site down, at least long enough to fix it. It'll be back up eventually (I've seen it happen before).

We salute every initiative that results in fixing FDB problems. We will wait for Syd to fix whatever issues he may have. What bothers us this time is the missing of any communication so we know what's going on, as well as how and if we could help. I am sure we have here people with a lot of experience in domain...

We hold our fists...

The a*b##+c spam started as soon as the database is recovered.....

chris2be8 · 2018-11-28, 17:55

It doesn't seem to have a worker to factor small numbers running so I've set one of my systems to clear them out.

I wish someone could visit whoever's adding the a*b##+c spam and apply some rubber hose psychotherapy to persuade him to stop.

Running fdb_auto.pl again to clear out the 75-78 digit range.

The DB has been hit again with the "random 100-digit string" spam, adding composites at a rate of ~150 per second. We really need some countermeasure against this.

What about a system of referrals whereby trusted parties can endorse submitters?

I pointed a core at 78 digit composites.

Managed to thin out the mess in the range of 90+ digits by a bit... It turns out a significant portion of composites in this range were added to the database in a "non-standard" way, so they did not went through the "pick out small factors" phase. Requesting the composite list in "text-only mode" seems to force the database to do this preliminary factorization to everything in the requested range.

Anyway, the total number of composites under 120 digits went down from 905k to 895k for the moment, and a lot of C100+ had become C90-. (To think this total was around 400k just a month ago..... )

It's down again.

It started saying "Migrating to a new server. Offline for ~24h." for about a minute, then it started saying "Could not connect to database". So I'm not sure if the first message is true.
