Hi Ilia,

My 28-month-old forum has worked perfectly the whole time until yesterday. Suddenly it's only offering a blank page.

Apache's running. MySQL is running. I can query the forum database over ssh, and Serendipity - which uses the same db server on the same site - is running normally. But take a look at this:

Two questions here. Firstly, it looks as if practically all the recent messages were written to the same, very large file, msg_80000. Secondly, the permissions aren't the same across all message files and I've no idea why.

I suspect the size of the file is causing the problem - it's so big it could conceivably cause a timeout - and would appreciate tips on fixing that. Also, is there anything I can do to limit the message file size in future, or is this a known/fixed problem with older forums? (I'm about to move to a new server and will upgrade FUDforum then).

If it isn't the filesize that's at fault, any clue would be good right now..

Thanks,

- Steph

All speculation. Can you please check your webserver's error_log and post the fudforum related messages here?

The actual problem's resolved - the session table was corrupted - but it still seems odd that msg files could get so big. Is there no way to limit the size?

There is a "Compact Messages" option in the Admin Control Panel.

However, please backup your message files and DB before trying. If something goes wrong you can lose your entire forum.

I already pressed that button (and yes I'm well aware of how it all works thanks). With that + the various cleanups I got the biggest files down to roughly a quarter of their original size, but new messages are still being added to the same file and it's _that_ I'd like to prevent.

I'll mail Ilia and see what he says.
