[Condor-users] One node doesn't execute jobs

["Smith, Herb" <herb.smith@xxxxxxxxxx>]

All,

I have a very simple pool consisting of 3 nodes.  The master node is a Windows7 machine and the other two are Windows XP.  Each machine has a dual core processor and Condor correctly sees all 6 processors available.  I included the logic to ensure that both types of operating systems would be used:
Requirements   = (OpSys == "WINNT51" && Arch == "INTEL") || (OpSys == "WINDOWS" && Arch == "X86_64")

Which seems to work fine, with one exception.  The master node and one of the two pool members accept jobs, the remaining pool member shows a status of "Matched" but it never shows that it was "Claimed" nor does it run any jobs.

Here is a typical inquiry:

Both of the pool machines have the same operating system setup as all the machines in the company receive the same software load.  Is there some way to determine why this machine is not picking up any of the work load?

Thanks,
