[Condor-users] IDLE jobs

["Hrant P. Hratchian" <hhratchi@xxxxxxxxxxx>]

We're experiencing something somewhat odd with Condor.  Presently, 
all of our nodes are for production only (i.e., none of the machines 
are used as workstations) and the START ClassAd on all machines is 
statically set to TRUE.  The machines all have 2 processors and we 
haven't tinkered with the virtual machine settings, so the number of 
VM's per node is 2.

Here's the actual problem...Two jobs were sent to node-5.  The other 
nodes in our cluster became saturated with jobs and the Condor 
scheduler somehow sent another job to node-5.  When this happened the 
status of the first job started on node-5 became "I" and the new job 
had a status of "R".  As I understand things, once the scheduler 
started the two jobs on node-5 a third job should NOT have been 
allowed at all since there are only 2 virtual machines.  What am I missing?

Thanks,
Hrant Hratchian
