Hi,
here is my issue:
under certain circumstances weird device overflow is mounted to /tmp
Code:
# mount
Code:
......
overflow 1.0M 436K 588K 43% /tmp
At the same time there is no even a hint in fstab:

Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/sda1 / ext3 errors=remount-ro 0 1
/dev/sda6 /home ext3 defaults 0 2
/dev/sda5 none swap sw 0 0
Also, there are a lot of deleted files in /tmp directory were notified:

Code:
# lsof /tmp
Code:

Question is: why does it happen and how to avoid it?
