/tmp running out of inodes

[Tankko]

For the second time in 2 weeks my server has gone down due to running
out of inodes in /tmp.  The first time it did this /tmp was filled
with files, so that made sense.  I delete all the files from /tmp and
all was well for a few weeks.  Just this morning it did it again (keep
in mind that this sever is currently 700 miles away) and had to be
rebooted.

But when I looked at /tmp, it was empty except for a couple of files,
but running df shows the follow:

Filesystem     Size    Used   Avail Capacity iused    ifree %iused  Mounted on

65790 used inodes and 0 free on /tmp

I ran fsck and it shows:

** /dev/ad4s1e (NO WRITE)
** Last Mounted on /tmp
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
65790 files, 35374 used, 218441 free (9 frags, 27304 blocks, 0.0% fragmentation)

So where are these mysterious 65790 files?  Is there a way to clean
this up?  And more importantly is there a way to do this remotely
given that I am 700 miles from the server right now?

Every time the server goes down due to this problem, it won't come up
again without someone physically running fsck at boot.

On a side question...what the the best policy for deleting files from
/tmp?  Seems like a lot of apps are happy to leave files in /tmp.  Is
clean up commonly done as a cron job?  What about files like
mysql.sock= which are important.  I can't just blindly remove
everything in /tmp each night.

Thanks for any help.
