Apache 2 + Fastcgi + suexec configuration trouble

Hi,
I’m installing RT 3.4.4 on Linux with fastcgi + suexec. When starting
apache, all fastcgi processes dies with exit code 103.
Looking at google and fastcgi site, I cannot find any tip about what is
causing this error.
Bellow is an piece of error log :
