503 Service Unavailable - What is the problem with PHP ?

[lamnk]

All of sudden i get this message from every PHP sites (static only pages are ok):

503 Service Unavailable
The resource requested could not be found on this server!

"tail -f stderr.log" constantly shows:

2009-03-27 17:27:26.460 [STDERR] lscgid: setuid(): Resource temporarily unavailable

I've tried to upgrade Litespeed to 4.0, get the newest LSAPI and recompile PHP. The errors stay the same =( Please help

Problem solved.

It was a badly programmed script that get cron'd. After i kill every instance of it (there are a lot !) then my sites are back.
