fastcgi problem

[Vuki]

Hi All!

I have got a problem with my fastcgi backend.
A have a fastcgi server listening on a TCP docket (also tried unix 
socket as well).
The fastcgi server randomly dies.
There is nothing in the nginx error log, nor in the php error log, nor 
in syslog.

How, where can i find debugging information about fastcgi backend?

thanks!
