I'm having problems with ULIMIT -n:
Once having stuffed eclipse with several plugins, it's keeping all those jars open, thus running out of file descriptors.
So I first naively tried
ulimit -n 4096
and got:
bash: ulimit: open files: cannot modify limit: Operation not permitted
Searching the web, I got serveral hints, all to no avail:
Hint one: configure /etc/security/limits.conf
I tried the following entries.
* soft nolimit 4096
* hard nolimit 65572
eclipseuser soft nolimit 4096
eclipseuser hard nolimit 65572
root soft nolimit 4096
root hard nolimit 65572
This did help for root, but had no effect for the other users,
even after reboot (asside: would a reboot have been necessary?)
Hints two to n: place ulimit -n 4096 in any of:
/etc/profile
/etc/.bashrc
~/.profile
...
where ever I tried that, I got
bash: ulimit: open files: cannot modify limit: Operation not permitted
unless, I'm running as root!!
Well I'm feeling a bit quesy running eclipse as root with all that plugins.
So how do I *really* expand the filelimits for a non root user? Preferably without having to sudo?
Oh btw. I'm now running xubuntu HH on AMD64, but had the same problem on GG.
