"Too many open files in system" show in the maillog

[borgliu]

Hi, All
I have a R.H Linux , kernel 2.2.12-20. for mail server.
for last few days, I'm encounting the problem that mail can't send completed.
I checked the maillog, I found "too many open files in system"
because my system memory only 256MB,
Is any parameter can modified to solve this problem??
thanks.

This is because the compiled ulimit's are too low.

To check to see what limits are set on your server do:

% sysctl -a | grep maxfiles

In the case they are too low, you will need to recompile the kernel with the MAXUSERS set higher.
