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

It is better set PHP_LSAPI_MAX_REQUESTS=500 or 1000. You don't want a child php process just serves one request and exits. Max Idle time by default (not set) is -1 (server never kill the parent PHP process). Another possibility of opcode cache reset is server restart (by itself). You can verify the server uptime in realtime stats and see if it does restart often (uptime is short). if so, you need to check error.log around the time it restarts for clue.

[NiteWave]

also, you change the default setting
PHP_LSAPI_CHILDREN=35
to
PHP_LSAPI_CHILDREN=50

then have you changed
Max Connections:35
as well? should change it to 50 as well. these 2 settings should match

Ok, something is definitely restarting the litespeed server. Just have to figure out what and if anyone has any tips on how to go about that I am all ears. Here is what is in the info log from the litespeed admin panel after a recent reset.

[NiteWave]

does it happen often?

[NUTNDUN]

Seems to be averaging about once an hour or so, it isn't consistent either, like one time it might be 45 minutes and then the next time it might be an hour and 15 minutes. So far the highest hits I have been able to get on xcache has been 195,000 and that lasted about an hour and fifteen minutes.

We do have configserver plugin installed on this one but we also had it on our last vps. Clam AV is also on it and we didn't have it on the other server.

[NiteWave]

so the issue is: lsws restarts about once 1 hour in unknown reason, and that can explain the cache reset issue. true?

[NUTNDUN]

Yes that seems to be the issue.

[webizen]

Did you get email from cPanel when LSWS was restarted?

No, I am not getting any emails about LSWS being restarted. I get emails if I goof up trying to login the the LSWS admin panel though.
