Hi,
on the hosting of a client, it appears the 503 error when we open the index. The CMS is prestashop.
we found this in the log:

The error below (from your error log) indicates php crashed. lsapi tried to recover connection and failed (Max retries has been reached) to connect PHP which is crashed. Usually, should let PHP dump core file and find out what the root cause is.

if 503 error is due to consistent PHP crash, you can add environment variable

LSAPI_ALLOW_CORE_DUMP

to lsphp5 external app configuration to let PHP dump a core file.
(http://www.litespeedtech.com/php-litespeed-sapi.html)

then check the core file with
gdb /usr/local/lsws/fcgi-bin/lsphp5 core_file_name
bt

It lists the stack call backs when PHP crashes, you can get some clue from it or send to us.

It could be bad PHP code causing infinity recursive function calls, one function call itself, which causes stack overflow.
You have to review the PHP script.

How can we check error if we can not see any error neither in error_log or from gdb ? This is a simple prestashop code.

if "bt" produce hundreds or thousands of entries like you posted, the php code causes stack over flow.

you can see an example at
http://ilia.ws/archives/5_Top_10_ways_to_crash_PHP.html

you need review PHP code or ask help from the people who wrote those PHP code.

by chance it could be Zend Optimizer? I've never had it play nice with my php installs, so I never installed it again :D

If you don't need Zend, disable it :)

Also maybe try stracing the php process.
