Re: FastCGI + Apache2 + php4fcgi

Hello Tom,

This is the reply of my question from jancha <[email protected]>
It might have something to do with the problem you are having.

------------------- cut --------------------
1) "Internal Server Error" - you get such error displayed if the underlying
program crashes for whatever reason.

2) Typically, if there are more than 3 crashes in 30secs, FastCGI puts a 
600second delay before launching a new process. Theoretically, you can patch 
the fastcgi apache module. No other workaround for this.
------------------- cut --------------------

Best regards,
Jack
