Constantly logged out

Assuming it’s a dreamhost problem... unpredictably logged out with internal server error. When I refresh after the error, I am logged out.

I'll check the logs to see if there's anything particularly interesting in there.

All I see is that you have, in fact, gotten some 500 errors. Nothing more interesting than that unfortunately.

Thanks. Today I’m just getting logged out frequently without errors...

As far as I know no configuration has changed and I don't see anything particularly weird in the logs. Weirdly, I'm unable to log in to the admin control panel to see if there's anything odd going on with the sessions table. Hmm.

Looks like another fucking search bot is DoSing the server through some overeager spidering. Sigh. Gonna do some IP banning...

Yep since I responded 20 minutes ago, got a 500 and was logged out. I’m wondering if the session is stored in memory or keyed on process ID in temp, so when php-fcgi dies, so do sessions. But it seems nobody else is complaining about this? Thanks for looking into it.

The longer 500 was because I was inspecting the sessions table and the DoS behavior of the bot was causing some massive database contention, or something. I've banned the DoS-y bot and purged the sessions table and everything seems back to normal, so now everyone will have been logged out but hopefully things will run better for a while.

Ugh, I’ll see if I can figure out what’s going on. phpBB is due for an upgrade, incidentally, but I’ve been asked to wait until Nur Ein finishes.
