eva2000, done.

Erwin, which kind of info exactly?

I've been told the server goes down due to a LOOP caused by a PHP/MYSQL call...

Does any1 know of any hack that would cause this/Has caused this in the past with VB 2.x series?

id guess its squalls call on the arcade hack

Ok i'll try to disable this and see if server keeps alive...

Use vbulletin's debug mode to display the query load how many are being made and how long each takes. That way you can get a closer fix on what the problem is.

I can now say it's not due to VBPRO ARCADE.... Server went down twice after turning the arcade off...

I already have microstats enabled and I monitor both the queries and server load from there...

I've seen VB working with PRO ARCADE enabled with 500 users online and server load be 0.85, so I DON'T THINK it's VB itself, but some sort of loop (as adviced by the server administration dept.) that it's causing the server overload (once it starts going up, load won't stop until apache and mysql go down).

Problem is mainly identifying the source of the loop...
:(

It might not be vB - it might be the way your server is set up, or a cron job. Does this happen at the same time each day?

It's a standard Rackshack (now EV1) dual xeon server, quite "normal" afai understand...

And no, it's not a cron job.

I have the same server. :) I have an ev1 dual xeon with 4Mb RAM. How busy is your server? My loads were fine on vB2. Do you need more RAM?

4Mb Ram? wow! ;)

I just have 1Gb RAM...

But I'm afraid whatever the bug is, it would consume the whole thing no matter how much resources I add, as it seems the load is only stopped once services (apache/sql) fail.....

And the server is NORMALLY not that busy, which means that in normal conditions, it averages 0.8x to 1.x load averages... Far from the 4.x maximum permitted...

What other hacks do you have installed?, you need to find this loop and kill it/optimize it.
