Latelly we’ve been experiencing huge slowdowns on the server running OTRS. It only runs OTRS and nothing more, so there is no other process that may be using mem/disc/cpu.

15:20:35 up 20 days, 3:19, 1 user, load average: 78.75, 101.80, 87.94

189 processes: 186 sleeping, 3 running, 0 zombie, 0 stopped

CPU states: cpu user nice system irq softirq iowait idle

total 1.7% 0.0% 13.5% 4.9% 0.0% 79.7% 0.0%

Mem: 384200k av, 379252k used, 4948k free, 0k shrd, 1180k buff

280884k actv, 67428k in_d, 1292k in_c

Swap: 915696k av, 722552k used, 193144k free 11108k cached

The problem is, as you can see, with the memory usage. Sorting the top output by mem usage, I can see that I have lots of httpd processes each with 20M of mem usage.

Doing a ps auxww | grep httpd | wc

I get 133 processes running.

The only way to solve this problem is to restart the apache server.

Does it has anything to do with session timeout? Anyone experimented similar problems ? Solutions ?

Thanks in advance,
