Re: [Condor-users] How can I check whether my VMware job is really checkpointed?

[David Kotz <dkotz@xxxxxxxxxxxxx>]

Rob,

If you look at the timestamps on the two checkpoint messages you'll see
that they're just 8 seconds apart.  It looks like a checkpoint was taken
and then the job was evicted 8 seconds later.  When the job was evicted
no additional checkpoint was made because it was too soon after the last
one.  Job eviction normally triggers an automatic checkpoint, but there
seems to be some minimum amount of time since the last checkpoint before
Condor will do another one.
