There is not enough memory on the server. The domain php.ini is customized, contains misprinted errors, or an invalid configuration. Permissions on the /etc/passwd file are incorrect. A problem with particular php module compatibility. Resolution Make sure PHP is compiled with FastCGI.

We are experiencing random "Connection reset by peer: mod_fcgid: error error reading data reading data from FastCGI server" errors which cause a 500 internal server error. If the page is then reloaded it loads normally as it should. We are running MPM Worker with mod FCGID to handle PHP. We had APC cache enabled but disabled it recently to see if it would fix the problem, but the random mod FCGID errors are still continuing. No other opcode cache is active now. Our settings are below:
I have observed the following error message in Apache's error.log: [Thu Jun 27 19:27:50 2013] [warn] [client xxx.xxx.xxx.xxx] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server [Thu Jun 27 19:27:50 2013] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: xxx.php My setup consists of Apache 2.2.16 (with MPM worker), mod_fcgid 2.3.6 and PHP 5.3.3. The error message appeared only when the web server was serving requests at a rate of approximately 20-30 requests per second. Below, I will present the troubleshooting steps that I used in order to discover what was the problem. To cut a long story short (tl;dr) you can read the last paragraph titled Special PHP considerations here: http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html#examples. In order to further investigate the problem, I've written and executed the following script (which was adapted from here: http://www.commandlinefu.com/commands/view/8097/easily-strace-all-your-apache-processes): ps -ef | egrep 'apache|php5' > processes cat processes | awk '{print"-p " $2}' | xargs sudo strace -f -o strace.out -t & This script traces system calls for every Apache or PHP process in the system and also follows any possible fork of the those processes. I left the script running, while I was monitoring the error.log. When the error message appeared, I terminated the script and began to investigate the trace output produced: 1) First of all, I searched for the error message, since I suspected I could find the respective write system call: $ grep 'Jun 27 19:27:50' strace.out 12403 19:27:50 write(15, "[Thu Jun 27 19:27:50 2013] [warn"..., 169) = 169 12403 19:27:50 write(15, "[Thu Jun 27 19:27:50 2013] [erro"..., 131) = 131 2) Indeed, process 12403 writes to file descriptor 15 (which is probably the error.log) the error message. The next thing I wanted to do was to check what this process was doing before emitting the error message: $ grep -C1000 'Jun 27 19:27:50' strace.out | grep ^12403 12403 19:27:50 ) = 1 ([{fd=43, revents=POLLIN}]) 12403 19:27:50 read(43, "GET /info.php?id=109&state=live "..., 8000) = 675 12403 19:27:50 stat64("/var/www/penny/htdocs/info.php", {st_mode=S_IFREG|0664, st_size=311, ...}) = 0 # lookup and read .htaccess 12403 19:27:50 stat64("/var/www/penny/htdocs/info.php", {st_mode=S_IFREG|0664, st_size=311, ...}) = 0 12403 19:27:50 semop(12517376, {{0, -1, SEM_UNDO}}, 1) = 0 12403 19:27:50 semop(12517376, {{0, 1, SEM_UNDO}}, 1) = 0 12403
