[Condor-users] Distinguish preemption from crash

[Horvátth Szabolcs <szabolcs@xxxxxxxxxxxxx>]

Hi,

We have some jobs that tend to fail once in a while because of temporary 
memory / disk / network issues. Restarting the jobs usually solve the 
problem
but sometimes there are issues that make a job always crash, so 
restarting it unlimited times is just a waste of processors.
When not having preemption enabled we used to limit the restart limit 
(by using an on exit hold expression after n restarts) but
enabling preemption caused lots of problems since - from the job run 
count classad variable - there is no difference between preemption
and a software problem and preemptions made reaching this restart limit 
quite fast.

What would you suggest doing to get around this problem? Can I somehow 
substract the number of preemptions from the job run count?
Or should I add a custom attribute to count just the software crashes 
based on the return values?

Cheers,
Szabolcs
