suexec/fcgid problem - error 500

[GioMac]

Hi,

Don't know why, but on one of my environments faced with problem running php scripts with fcgid, tried to find differences between them - no luck... When i do some manipulations with suexec - it runs, but in case root, few times was able to get scripts running with virtual user, with insecure way, but it didn't show "Loaded Configuration File" path in phpinfo.

How it's possible to get full debug for both fcgid & suexec runtime?
