tmp weirdness

W

wonslung

I was noticing a problem with a particular web application i have....it was acting like it was out of space, so i did a df -h

It was showing /tmp was 100% full...when i went to tmp, i could only find a couple largish files....after deleting those, it's STILL showing 98% full...i'm totally lost as to why this should be.....

this is a ls -al
Code: 
drwxrwxrwt  10 root     wheel       512 May 18 05:41 .

and here is a df -h

Code:

any idea what could cause this and better yet, how do i fix it
 
followup:

Weirdly enough, umount -f /tmp mount -a seems to have fixed it.
Code: 
/dev/ad4s1b                   496M     42K    456M     0%    /tmp
 
If a process still has the file open deleting it won't release the space.

Click to expand...

This may be true, but there wasn't that much space to be FOUND.

I had 2 log files in /tmp which took up maybe 10-20 MB of space. everything else was just plain invisible.

the only thing i can figure is something was still holding the space and i couldn't find the process.


anyways, i'll monitor it and see if it happens again....this is the first time i've ever seen this before.
 
See if the mountpoint itself doesn't contain files (boot in single-user mode, don't mount any devices, and check the /tmp directory).
