High CPU load with Litespeed 4.0.3
After an update to Litespeed 4.0.3 and a server reboot (kernel update) the CPU load is occasionally stay at 100% for no reason making the server unresponsive. Before the reboot everything was fine, load stayed from 0.xx to 1.xx
Does anyone have the same problem ?
Server's info: CentOS 5.3, kernel 2.6.18, php 5.2.8, mysql 5.0.45
Here is my top output:
You can "strace" the lsphp process keep using a lot of CPU cycles.
strace -tt -T -p <pid_of_lsphp>
Thanks, i ran the command, but i don't read its outputs, they read me ...
Anyway i installed APC cache for PHP, and the situation is now improved a bit. Look like APC trades off some memory for CPU time.
The problem seemed to be authentic load caused by badly programmed wordpress and its plugins. But i'm not really sure about that.
