Hello,
any body knows how/where dump files from litespeed will be created?
I have my public_html directory full of files named core.(some random numbers).
and I made sure that I disabled core dump.

very weird.

Likely produced by PHP processes. better check it with GDB to find out what causing it.

yum install gdb
gdb /usr/local/lsws/fcgi-bin/lsphp5 <core_file_name>
bt

maybe submit a bug report to PHP group.
If "LSAPI_ALLOW_CORE_DUMP" is set for lsphp5 external app, you can remove it, it can prevent core files from PHP, however, it is better to find out what is the root cause and fix it.

You should report this problem to PHP group, bugs.php.net . call stack back trace should be helpful.
And, you can try downgrade PHP to 5.3.4 or 5.2.17.

remove it from environment. Again, it does not fix the problem in PHP engine, just prevent the core dump files from producing. Better switch to a PHP version does not have this problem.

I couldn't recompile, whenever I recompile my application doesnt work.
I used the options in phpinfo page and I missed some extensions like PDO_mysql and lost the php.ini custom config. and still didn't work (im running magento).
I went to the compile option in the admin panel, and then I chose "Use Configuration from previous build" and didn't work too..
