Good Day, Running ISPConfig 3.0.5.4p3 on Centos6.6. My sites suddenly stopped working? I get a 500. ISPConfig still works? So doesn't seem to be an Apache issue? Not a ressource (Ram, CPU) space issue. # df -h Filesystem Size Used Avail Use% Mounted on /dev/ploop23659p1 40G 19G 19G 50% / none 4.0G 4.0K 4.0G 1% /dev none 4.0G 0 4.0G 0% /dev/shm I see this in the sites error logs?

Could it be that something changed with the site (customer not using APC cache and now yes?). I'll double check with the customer at the same time... Seems to be a write ussue??? Thank you, JP
Seems as if apc cant write to /tmp anymore. Maybe the permissions of /tmp has been changed or one node has mounted /tmp partition in read only mode. Check that the /tmp directory is world writable on bothe servers.
I double checked the Node: drwxrwxrwt 3 root root 4096 Jul 5 03:21 tmp Rebooted the VPS and checked the VPS: drwxrwxrwt 6 root root 217088 Jul 5 11:05 tmp Still having errors...: [Sun Jul 05 11:12:36 2015] [error] [client 74.86.158.110] PHP Fatal error: PHP Startup: apc_mmap: mkstemp on /tmp/apc.clVhhg failed: in Unknown on line 0 [Sun Jul 05 11:12:36 2015] [error] [client 74.86.158.110] Premature end of script headers: index.php [Sun Jul 05 11:12:36 2015] [error] [client 74.86.158.110] PHP Fatal error: PHP Startup: apc_mmap: mkstemp on /tmp/apc.tamlWj failed: in Unknown on line 0 [Sun Jul 05 11:12:36 2015] [error] [client 74.86.158.110] Premature end of script headers: index.php [Sun Jul 05 11:13:11 2015] [error] [client 74.86.158.110] Premature end of script headers: index.php [Sun Jul 05 11:13:11 2015] [error] [client 74.86.158.110] PHP Fatal error: PHP Startup: apc_mmap: mkstemp on /tmp/apc.QKhrWt failed: in Unknown on line 0 [Sun Jul 05 11:13:11 2015] [error] [client 74.86.158.110] Premature end of script headers: index.php the /tmp in the website folder was at 750...

I will double check with the developper team if it's needed or anythig was changed ? Don't think they did any update on a site on a saturday. Thanks, JP
