I’m having issue with a cups print server throwing the same error. I’ve increased the max file system wide as well as in limits.conf…cups still thinks 1024 is the default so it only allows 1/3 (341) connections…Thoughts?

Yup, ulimit will be user specific and sysctl method system wide. Since my box is for DB only it does not worry me too much.

Thanks for the highlight man

After researching a lil further, i found that the limits.conf only places the limits on the graphical login.

if you want to put it on services. put the ulimit command in the boot script.

One limitation i see of setting the FD limit in sysctl.conf is that it applies to every application. Unless you want every process to get that many FD’s. I would go for the boot script way of setting FD limits.

Thoughts?

For SuSe (10.3) boxes you can do the same with the ulimit command
ulimit -Hn
-H to set hardlimit
-n to set number of open file descriptors

or you can manually do it in
/etc/security/limits.conf
