LSPHP5 cpu issue
Hello,
I'm running a rather large vbulletin forum with VBSEO but sadly it appears I am unable to get any stability going with litespeed. My CPU will often jump up from around 16 to 100+ or more and I'm unsure as of why, assistance would be appreciated.

run "top -c", you may see vbseo is consuming most of the CPU
google search "vbseo slow", can find many discussion there.
if php in non-suExec mode, APC/Xcache may be better than eAccelerator. eAccelerator 0.9.6.1 don't support user variable cache, while APC/Xcache does.
some application(vbseo maybe,not sure) may utilize user variable cache for better performance.

Hello
I tried APC but sadly always got 503 errors with VBSEO, I tried Xcache and this seems to work good so far, load is manageable (but I wont hold my breath).
I'm using my vbulletin database cache as Memcache and vbseo's caching options as Xcache so hopefully this will assist allot.
Thanks.
/EDIT
Still having load issues;

not sure if this helps:
http://www.vbseo.com/f77/100-cpu-usage-vbseo-24904/
"Changed Limit URL Length (was set to 255) to 0 - immediate drop in CPU load, application now performs exactly as expected."

That didn't alter my load at all really, my current stats and have been around this for about 12 hours now except every half hour or so it will spike up to around 50.

It will average between 30-100, nothing has been altered, I'm using memcached and xcache.

can you strace one of lsphp5 process which has run longest time, in your post, this one:
22172 nobody 16 0 272m 69m 40m R 6.7 0.9 1:24.27 lsphp5:/home/xxx/public_html/forum/vbseo.php
and see what it's doing.

Update;
It seems to be correcting itself again, allthough I made two alterations, I disabled vbulletins live topic and vboptimize, given that the optimize was already built into the configuration of vbulletin (memcached) and using xcache with vbseo , it appears to be "ok" as of this moment, but I'm sure it will go haywire shortly.

please note those lines with "Timeout", I think this may be an important clue. Many lsphp5 process are waiting something and get timeout, this will cause high load. I guess maybe waiting for responses from MySQL. most likely code bug somewhere, cause high load under some conditions.
