Please enable debug logging with "killall -USR2 litespeed", make sure "Log Level" is "DEBUG", "Debug Level" is "NONE" in advance.
Also, you can run "strace -tt -T -p <pid_of_one_litespeed_child_process>", the output will help debugging the issue.

I didn't find any 503 or 408 errors in access logs and Log Level it was set to "ERROR" which no any abnormal row was it in error.log

I see a few lsphp process running when it hung

DEBUG Log Level has been enabled to see whats wrong exactly,

but in fact i can't risk on this server because of customers that will get timeouts in case of this issue occurrence and added a cronjob to restart the lsws frequency

Do you have any suggestion to use another script instead of restart? It may doesn't log the reason of this issue but it restarts
I mean an script which can detect this issue very immediately and forces restarts then

Thanks in advance
