Trying to use APC but it seems to be clearing out?

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)

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)
        |                                     `-{litespeed}(28256)

Yes.. My APC is restarted every 30mins-3 hours, (more frequent at peak traffic).

please watch the result after set "Max idle time" -1

i've set it to -1 about 1 h ago, but my apc was restarted 20 minutes ago.. Any log that i should check?

[NiteWave]

my apc was restarted 20 minutes ago..

please memo down the pid of parent lsphp5, see if it changes too.
in your previous post,

litespeed(28252)-+-lsphp5(28271)-+-lsphp5(32446)

parent lsphp5 pid is 28271

Here is my result now

root@mybox[~]# pstree -p | grep litespeed
        |-litespeed(10551)-+-httpd(10552)
        |                  |-litespeed(10553)-+-lsphp5(10559)-+-lsphp5(14546)
        |                  |                  |-{litespeed}(10555)
        |                  |                  `-{litespeed}(10556)
        |                  `-litespeed(10554)-+-lsphp5(10595)-+-lsphp5(13525)
        |                                     |-{litespeed}(10557)
        |                                     `-{litespeed}(10558)

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

[NiteWave]

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.

grep "Server Stopped" in error log, check log entries before it.
