[Condor-users] Only 40 condor_shadows running on windows

I am submitting 2040 jobs to a 900+ node windows condor pool and for the life
of me I can't work out why I am only getting a maximum of 40 condor_shadows
running concurrently on my submit host. BTW condor_q reports that currently 270
jobs are running, 1766 are idle, and 4 have completed :) - How can 270 run
concurrently when there are only 40 shadows running ?
It's not lack of RAM (2G) or CPU (Dual Xeon 3.2) or Network (100 MBit). It's
not my condor config file as MAX_JOBS_RUNNING is set at 20000 and RESERVED_SWAP
is commented out so in theory condor should soak up everything available with
condor_shadows up to 20000 of them.
Does anybody know if there a limitation in condor for windows or in windows
itself re running more than 40 condor_shadow processes concurrently. Does each
condor_shadow manage more than one remote job at once? BTW Each job lasts about
an hour and a half so it's not that the jobs are completing fast.
I hope somebody can clear up this conundrum...
Thanks in advance
