Are you running the latest version of litespeed and lsapi ? If you are running 4.2.4 or less and cloudlinux you need to update litespeed and lsapi. If this is not the case then wait for litespeed staff to answer :)

Supposing you are in cPanel, run build matching php version from inside the litespeed plugin.

It will probably detect that you aleady have the same version of PHP but will give you the option to force the rebuild anyway.

When we last tested xcache it regularly crashed php. This could be the cause of the 503 errors.

For PHP 5.3 we're going to give apc another try with the processgroup mode and for PHP 5.5 we will be going with Zendopcache for PHP 5.4 not sure yet which one to choose !

Try setting PHP_LSAPI_CHILDREN to higher value like 100 for example. You should see zero 503 errors or a lot less.
I have already open ticket regarding this bug, I think the solution is on it's way.
For now temporary fix is just to set PHP_LSAPI_CHILDREN to a high value, depends of how php busy your server is.

Same issue here today. Running PHP 5.4 with OPcache and Zend Optimizer enabled on a cPanel box.

Getting these suddenly:
connection to [/tmp/lshttpd/lsphp5.sock.780] on request #1, confirmed, 1, associated process: 4791, running: 1, error: Connection reset by peer!

Running LT 4.2.10

config attached for lsphp5 (assuming this is the one I would edit since I'm running PHP 5.4 not 5.5)

max connections:250
PHP_LSAPI_CHILDREN:100
===>not match. keep them in same value.

and please set
Run On Start Up: suEXEC Daemon

this will make opcache much more efficient
