Problem with numproc and cachesize

rdiaz82 · Jun 16, 2013

Hi!

I have reinstalled a instance with Pararell Plesk 11 and I have configured three domains in that instance. I donÂ´t know why but every 4 or 5 hour the number of mail process start to increase and the system is blocked and I have to reboot the instance to solve the problem...

Here is attached a process list before reboot the instance in one of this situations:

Code:
