Topic: SME 6 start running at 100%

[Pierre BOUCHER]

Suddendly, at about 6pm, my server on witch i run a postnuke website, start averaging a 100% cpu load for no apparent reasons

I didn't change anything on the server.
When i redirect the users on a static page, the cpu load drop.

Also, 5 minutes after a reboot the DB_pnphpbb2 forum stop working.

The rest of postnuke still running fine.
But CPU still at 90%+

I redirect the main server on another PN configuration, still the server go over 90% load
With 4 users.

Normally i run at 5% average.

I'm in big troubles!!!!

Any ideas!!!

If looking at top each httpd processes generate about 20% cpu load. I tried opening a php-nuke site an oscommerce, a postnuke each request cause a 17 to 25% load.

System is a celeron 500 with 256mb ram.
like i say before everything ran flawlessly for the last month or so.
