since the message is "
out of file descriptors: Too many open files in system; release and retry" i think you should also be checking the system ulimit.
try commands like "ulimit -a" to check the number of files currently open in the system. Also try "ulimit -Hn" to get "The maximum number of open file descriptors (most systems do not allow this value to be set)" see man pages of ulimit for more details.
you could also increase the ulimit by making changes in "ac/etc/security/limits.conf".
However i hope you have already checked the possibility of some other process which might be continuously opening files and not closing it properly. Linux has a fixed number of fd's that can be used and if the process dont relese them it coudl lead to such a problem.
Hope this helps.
Thanks,

Did you request about kern.maxfiles?
