Bug#449345: exim4: daemon exits without notice when there is no disk space

[Paul van Tilburg]

Package: exim4
Version: 4.63-17
Severity: important

I am running an important exim4 server for dozens of users on Etch.
However, lately, when I notice that I do not get any mail anymore it seems
that the exim4 server has just exited/crashed, because it is no longer
running. When using QUEUERUNNER='separate', the queuerunner stays alive,
but after a while the stmp listener/daemon is dead.

After three days, I finally found something in the logs that might indicate
the source of the problems:
Nov  4 17:47:02 sphere exim[12843]: 2007-11-04 17:47:02 1IoicV-0003L9-DS failed to write to main log: length=205 result=142 errno=9 (Bad file descriptor)
Nov  4 17:47:03 sphere exim[12843]: write failed on panic log: length=118 result=-1 errno=28 (No space left on device)
Nov  4 17:47:05 sphere exim[12844]: 2007-11-04 17:47:05 1Ioicr-0003LA-HM failed to write to main log: length=183 result=-1 errno=28 (No space left on device)
Nov  4 17:47:05 sphere exim[12844]: write failed on panic log: length=122 result=-1 errno=28 (No space left on device)
[and so on...]

IMHO, the daemon should stay alive and try to log this or my change its
process name, appending [out of disk space] or something.

Regards,
Paul
