Hi,
I'm seeing a recurring problem whereby a users process is causing the
system to crash by (I believe) filling up the /tmp partition. Twice this
week this has happened shortly after I have renice-d a resource hungry
bittorrent download I've seen a user running.
I have sensible user block quotas set on the /home partition and
everywhere else besides /tmp that the users could be putting data, and
there is of course the 5% of space reserved on all partitions.
Everything divided into separate partitions as recommended. /tmp is
virtually unused most of the time so I can't figure out what might be
happening.
When the system comes back up everything appears to be fine, /tmp having
been emptied by rc. There seems to be nothing logged to tell me what
might have happened so I'm just left scratching my head.
Does anyone have any ideas, or suggest ways of getting more diagnostic
information?
Thanks
Mike
