I have to take it back.

you need to be in /usr/local/lsws/fcgi-bin/ to check lsphp5.

for below, it is likely you are in a different directory (.../php) that has a copy of php.ini with "extension=xcache.so" in it.

[root@poseidon php]# /usr/local/lsws/fcgi-bin/lsphp5 -i | egrep -i 'apc|xcache|eaccelarator'
with XCache v1.3.2, Copyright (c) 2005-2011, by mOo

However, your fcgi-bin/lsphp5 uses a copy of php.ini with *NO* "extension=xcache.so" (xcache not enabled). that's why 'fcgi-bin/lsphp5 -v' shows no xcache. To find out which php.ini your lsphp5 uses, do following.
/usr/local/lsws/fcgi-bin/lsphp5 -i| grep php.ini
Click to expand...
So in your case, lsphp5 doesn't not have xcache enabled.

I'm having problems. I used the build php with xcache and memcached check in the lsws admin page. I noted down the install directory for xcache.so

When I check php -v it says xcache is installed. But when I view a phpinfo on a web page no xcache is installed.

zend_extension = "/usr/local/lsws/lsphp5/lib/php/extensions/no-debug-non-zts-20060613/xcache.so"
[xcache.admin]
xcache.admin.auth = off
xcache.admin.enable_auth = off
xcache.admin.user = "test"
xcache.admin.pass = "098f6bcd4621d373cade4e832627b4f6"
;xcache.admin.pass = "53f018f2ee1fc4fb7ad2be1cc7b9ed43"
[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 256M
xcache.cacher="On"
xcache.coredump_directory=""
xcache.count="8"
;xcache.coveragedump_directory="/tmp/pcov/"
xcache.optimizer="Off"
xcache.readonly_protection="Off"
xcache.test="Off"
xcache.slots="8K"
xcache.readonly_protection = Off
xcache.ttl="3600"
xcache.gc_interval = 300
xcache.var_size = 4M
xcache.var_count = 8
xcache.var_slots = 1K
; default ttl
xcache.var_ttl = 3600
xcache.var_maxttl = 7200
xcache.var_gc_interval = 300

if you check from php -v i think it's wrong
try fcgi-bin/lsphp5 -v

if you check with php -v alsi it just chect your server
and not your litespeed CMIIW

example :

[root@xxxx lsws]# fcgi-bin/lsphp5 -v

maybe you refer:
http://xcache.lighttpd.net/wiki/Faq#Whyismycachebeingcleared

then how many litespeed processes are running on your server?
#pstree -p | grep litespeed

what you observed is just the reason why on shared hosting environment, only eAccelerator is recommended. all php processes can share the opcode cache under a single disk folder, like /tmp/eaccelerator. usually, php suExec is enabled in such environment. APC and XCache only keep opcode cache in memory. so each group of php processes will have its own cache.

Here it is (while i open litespeed admin on whm)
Code: 
root@mybox [~]# pstree -p | grep litespeed
        |-litespeed(28249)-+-httpd(28250)
        |                  |-litespeed(28251)-+-admin_php(32375)
        |                  |                  |-{litespeed}(28253)
        |                  |                  `-{litespeed}(28254)
        |                  `-litespeed(28252)-+-lsphp5(28271)-+-lsphp5(32446)
        |                                     |-{litespeed}(28255)

Here is my result now

Yes it is changed now, so it seems litespeed was restarted?

yes, if pid of litespeed changed, it must have been restarted.

litespeed may restart to fix 503 error automatically.
in a site with buggy php script, this may be helpful without whole site down.

Usually when i got an 503 error and LS was restarted, i got an e-mail notification. Why i didn't get any notification?

Is there any log that i can check to see why it happened?
I tried to open "Server Log Viewer" but there are too many.
