Problem with lsws- server hangups
 

Hello
I have a seriously problem with lsws. I host only one site on it . i have also bought a lsws license. While having high traffic lsws tends to not serve new requests , it hangups , only restart helps.

my logs

are there any special settings on pages having many amount of served requests?
any suggestions how to optimalize it

Please check WAITQUE_DEPTH of phpLsapi during a taffic surge, if it is very high, you need to improve you PHP/MySQL code, as it is not able to keep up with the traffic. You can try raising "Max connection" of phpLsapi, but it may not help much.

You can also looking into our Anti-DoS configuration: http://www.litespeedtech.com/how-tos.html#qa_dos
