Forgot about the stuff that matters(TM): Server running in a vmware ESX (hardware is a dual xenon 2.8Ghz, 6GB Ram, 200GB HD SCSI RAID5 on a DL580) VM has 400M memory allocated, 1 cpu 2.8Ghz, 10GB HD. VM running RedHat Enterprise Edition 3.0U1 OTRS 1.2.2 Mysql as backend DB on the same vm du -s /var/lib/mysql/otrs: 135M As I stated in the original post: - the number of httpd processes tend to rise over the time (starts with 10... in a day reachs easily 120) When this happens, the hardware CPU is at 5% , the emulated cpu at 70%, and the memory consumed is about 1.5GB inside the virtual machine. If the problem has anything to do with sessions being around too much time, the question is: where do I define the timeout ? in apache, in otrs ?

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,
Duarte Cordeiro
