Did you set the "FLOCK_FROM" macro in the condor_config for each pool?
Doing so then allows the negotiators from other pools to be authorized
to connect to the schedd, and from the looks of your log snippet I think
the schedd on master01 did not authorize the negotiator on master02 and
hung up the connection. (Do you see "PERMISSION DENIED" in the SchedLog?)
