Apache 2.2 + mod_fcgid + PHP 5.4: (104) Connection reset by peer
- by Michele Piccirillo
On a Debian 6 VPS, I'm running PHP 5.4 via mod_fcgid on a couple of different virtual hosts, managed by Virtualmin GPL. At random, I get 500 Internal Server Errors; restarting Apache brings everything back to normality.
Examining the logs, I find messages of this kind:
[Thu Oct 04 15:39:35 2012] [warn] [client 173.252.100.117] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Thu Oct 04 15:39:35 2012] [error] [client 173.252.100.117] Premature end of script headers: index.php
Any ideas about what is happening?
UPDATE: I found a similar question and the author reported to have solved the problem disabling APC. I tried following the advice, but I'm still getting the same errors.
