After upgrade from php 5.3 to 5.4 on plesk 11, i am getting these error messages.

[Tue Sep 03 14:12:45 2013] [warn-phpd] mmap cache can't open /usr/share/psa-horde/lib/Horde/Menu.php - Too many open files (pid 7836)

Even though the number of open files are 33000 and the ulimit is set to 45000, still i am getting this error. what could be reason for it?

it's plesk 11.5 or 11.0? Did you tried this KB kb.parallels.com/en/115139 ? –  Oleg Neumyvakin Sep 3 '13 at 15:48

Try to disable APC ( if have it ) and check again, maybe you have something wrong on config.

And have you a VPS ?

Some times is a memory problem if ulimit have a high value.

Check your sysctl.conf meybe have some soft limits.
