This is the part where you describe what you've already tried, so that we don't waste our time asking you to try things you've already done.

So, please feel free to describe the problem, and what you've already tried. Be specific.

What's suddenly taking up all the space? You have a core dump (find /var -name core -ls)? Some files have suddenly grown big unexpectedly (find /var -mtime -1 -ls)? What dir is taking up most of the space (du -sm /var/*|sort -n)? Or is it that /var is simply too small to begin with (df -g /var)?

Have you tried doing a du -g | sort -n?

This will give you a listing by number of what the largest files and subdirectories in the /var fs are.

The largest will be at the bottom.

Check /var/adm for a lot of pacct (process accounting) files. Or a large amount of "message" files.

If you find a large amount of pacct files, depending on the frequency that they are kept and how far back you want to be able to look at them you can safely remove all but the one active file which will be named "pacct" with no numbers following it.

Same holds true for the message files.

Good luck

Thought I might throw this out there...

If you find a file (or files) that's filling up the filesystem - don't delete them.
Instead, zero them out (cat /dev/null > file). That way, if a process still has it open, you won't be creating a bigger problem as it continues to fill up the filesystem.
