On 31st october and just now (2nd november) my CPU load was dropped to nearly zero. Seems traffic was not handled by server at all.

On 31st october i restarted mysql & httpd, and it was fixed, at that time i didn't know which one that fixed my problem. restarting mysql / httpd.

Now on 2nd november, when i restarted mysql, nothing happened. When i restarted httpd from WHM, everything back to normal. So it is the web server problem.

Last lsws config change that i had was (30th october) :
lsws > server > connections > max connections > changed from 2000 to 4000

Do you think that caused the error? Now i have reverted it back to 2000

After rebooting the lsws recently on lsws log i see lot of these lines.

Code:

this may relate to this setting:
lsws admin console->Server->Tuning->Connection Timeout (secs):default is 300, looks your setting is 120. right?

yes, you are correct. however i have downgraded php 5.4 to 5.3, do you think this problem will dissapear because of that?

Thank you.

most likely, if the root cause is php 5.4 not compatible well with APC.

you can search the log if it still exist after switching to php 5.3

Now is my peak hour and everything runs way faster than my peak hour on previous day :)
i think it's the result of combination of downgrading from php 5.4 > 5.3, change on the APC config, and little bit increase on litespeed memory soft & hard limit.

Here is my APC config just in case anyone wants to try.
