Subject: Re: [PHP-DEV] Fatal error 'Unable to read from thread kernel pipe' when using mail function
From: stuttle@gmail.com (Stut)

Ok, I've rebuilt Apache2 forcing the prefork MPM option. I then
rebuilt PHP4 and all the extensions. It's still doing it. What other
possible causes are there?

I did read in the results Google gave me that if the Apache2 MPM is
the problem then anything that pipes out to a system call will fail,
but I can use system and passthru without any issues. I'm fairly
certain it's not related to Apache2.
