500 - Internal Server Error when accessing panel

[Lewutan]

Hello,

I get this error message when trying to access plesk panel.

I have this in /var/log/sw-cp-server/error_log
DEBUGGER DETECTED... Bye!
2013-12-09 10:17:15: (mod_fastcgi.c.1068) the fastcgi-backend /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u psaadm failed to start:
2013-12-09 10:17:15: (mod_fastcgi.c.1079) terminated by signal: 9
2013-12-09 10:17:15: (mod_fastcgi.c.2889) ERROR: spawning fcgi failed.

I have tried restarting psa and all services.

I think the original problem came from the fact that /var was full and may be the last micro update went wrong. But this is just a guess.

Does someone know how to fix this ?

Problem solved

Thanks for your reply IgorG,

I have found what the problem was.

I had rebooted with the wrong home made Kernel provided by my supplier (OVH) which has GRSEC option.

Apparently it does not allow Plesk to kill its own processes.
