Plesk Domain Limit
by Tinuva on Jun.17, 2009, under Plesk
Well had an interesting case today of a plesk server dying on me with the error:
[Wed Jun 17 08:48:57 2009] [error] [client x.x.x.x] (24)Too many open files: couldn’t spawn child process: /var/www/vhosts/domain.com/cgi-bin/script.fcgi
Usually this happens at around 300 domains with most Plesk servers on Centos, at which time you enable piped logging to go further on the amount of domains you can have on the server. Today however we reached 1240 domains on server (not how I would run a server but resellers go crazy) at which time it just stopped working. The solution was to start getting rid of inactive domains that has been inactive for more than a few months to lower the total domains.
Perhaps I have missed something, but this is after all 32bit server where a 64bit server could go even higher.
