Re: [Condor-users] condor_submit hangs with warning on Mac OS 10.4

[Craig Bruce <pcxcb1@xxxxxxxxxxxxxxxx>]

I can confirm I also get this behavior occasionally on Mac OS X 10.4 (Intel
& PowerPC) with 7.0.x/7.1.0. The hanging and warnings don't stop the tasks
from running successfully though. Hangs tend to occur when requesting
multiple processes per cluster.

Cheers
Craig
