Thanks, i looked in suexec_log and found those lines

Also, did you execute cagefsctl --force-update after a switch? Maybe needed binaries are not there?

Im pretty sure the problem is one of the Fcgi limits is being reached. You can add my fcgi configuration in WHM "Apache Configuration" -> Include Editor - Pre Virtual Host Include

FcgidMaxRequestsPerProcess 500

FcgidMinProcessesPerClass 0

FcgidMaxProcessesPerClass 8

FcgidMaxProcesses 150

FcgidIdleTimeout 60

FcgidProcessLifeTime 540

FcgidIdleScanInterval 30

BusyTimeout 1500

IPCConnectTimeout 300

IPCCommTimeout 7200

Tweak it according to your needs or server.

Hi,

There should be more information in some other apache logs, most probably in suexec_log . The usual thing of such error after switching to FCGI are permissions and ownership isssues, for files and for directories.

Hello! Im trying to setup one server to use FCGI instead of suPHP. Its a shared server with 150 accounts. Every time i try i get error 500 on some sites. I check the file permissions and are ok, how can i debug this problem?

Here is a sample error from apache error_log

[Wed Sep 23 12:00:24 2015] [warn] [client 207.46.13.176] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Wed Sep 23 12:00:24 2015] [error] [client 207.46.13.176] Premature end of script headers: index.php

Thanks!
