Unfortunately no.  I have been seeing this behaviour 
for months now with torque_1.2.0p2,4,5 and 6.  From 
Maui I get:
HostList:
  [n504:1]
Messages:  cannot start job - RM failure, rc: 15041, msg: 
'Execution server rejected request MSG=send failed, STARTING'

Sometimes this is associated with a failure in the 
network.

I always either wait until those nodes eventually 
become free (and the job runs) or ask the user to 
re-submit.  However, sometimes when it attempts to 
start it a second time the same error occurs and I 
have to delete the job.

I've tried things like `qalter -lneednodes=  <jobid>`,
with no effect.

Does anyone else see this behaviour?

Simon.
