error of "/kernel: file: table is full"

[koeicjm]

I use freebsd 4.4 to run our server programs,
and after 2 days or 3days server becomes down,
and the messages log files always said :
/kernel: file: table is full

I think it is because there must be some file handles not
closed after used , so the question is that I want to know how can I get the numbers of current file tables .

#sysctl -a |grep kern | more
this will give you all the values in kern.something vars on the system
good reading is:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-kernel-limits.html

Operational system: FreeBSD 4.x-RELEASE
Message: "kernel: table is full"

This happens because the number of open files at the same time on the system is less than server needs.
To correct this:
1 - create or edit this file:
/etc/sysctl.conf
and insert or edit the line:
kern.maxfiles=16384
------
2 - or:
sysctl -w kern.maxfiles=16384

You need a custom kernel and in kernel configuration increase 'max users' -- I've set my to 256.
