im using 3.3.17

any ideas?

[mistwang]

It is hard to say what causes it to crash without a core file.
Please check error.log and stderr.log .
If you knew which request cause lsphp5 to crash, you can try strace the PHP process.

Please upgrade to 3.3.18, or to be released 3.3.19 package.

We suffer the same with latest version:

How can we find the cause ?

Regards.

[mistwang]

That's your fast cgi PHP binary crashed, if you can find the core file, you use GDB to get the backtrace of the call stack, then submit it to php.net.

[iCARus]

We use LSWS with cPanel so what can we do ?

stderr log is full of :

[mistwang]

That probably produced by a PHP script.

[iCARus]

How can we find that ?
