[Resolved] APC restarts often after upgrading from 4.1.13 to 4.2.4

[semprot]

My APC restarts often after upgrading from 4.1.13 to 4.2.4.
However i see that the litespeed itself "seems" not restarted (i checked the "uptime" from litespeed webserver > real time stats).

How can you help me to analyze whether the restarts is indeed caused by the upgrade?

Thanks.

If you do not use per user php.ini, you can enable PHP suEXEC daemon mode after compiling PHP with LSAPI 6.3 .

http://www.litespeedtech.com/docs/webserver/config/extapps#runOnStartUp

It will prevent APC cache from being flushed.

I think i only use 1 global php.ini.

About "runOnStartUp", is it a new feature that didn't exist on 4.1.13? (introduced after 4.1.13)
Because when i used 4.1.13 everything was fine.

Update: okay so what should i choose on run on start up box? "Yes" / "suExec Daemon"?
I am trying to choose "suExec Daemon" now & restarted the LSWS

Update 2: after watching for some minutes, APC uptime is still restarted to 0. Is there any other option that i should check?

Update 3: I've tried to switch back to 4.1.13 but APC still flushed, so i've switched to 4.2.4 again, and its not because of the upgrade but something else.

me@mybox [~]# free -m

Additional information : i use LSAPI_AVOID_FORK=1

please check the lsapi version, open a phpinfo() page, check the value of "Server API". if it's still 5.5, need rebuild lsphp with latest 6.3
