Apache Error 500 / SIGHUP received / FastCGI

[nicolas]

Hi,

I have successfully managed to migrate a VHCS2 install to ISCP Omega RC6 on a new server running Ubuntu 8.04LTS 64bits.

But now I face a problem: I got lot of error 500 while browsing the ISPCP panel (Edit: not while browsing other "php sites hosted on the server") and the apache error log is full of:

Quote:[Fri Aug 22 15:20:27 2008] [notice] SIGHUP received. Attempting to restart

[Fri Aug 22 15:20:27 2008] [notice] Apache/2.2.8 (Ubuntu) mod_fastcgi/2.4.6 configured -- resuming normal operations

Apparently this error appears only while browsing the ISCP Control panel, not regular sites (but it's too fresh to tell).
Any idea?
