Comment 2 for bug 265855

After some further research, QRUNNER seems to stop after
exactly 24 hours of operation. That is, 24 hours after qrunner
starts, it ends as if someone killed it with SIGTERM. I know
for a fact that nobody is actually doing this ... and no process
on my system should be aware of the fact that qrunner is
actually running.

I will not discount the possiblity that this is an environmental
factor, but it seems to me that a daemon process should not
be affected by environmental factors.
