Symptoms

RMAN backup hangs.
Debug trace shows we hang on a call to pcicmp during an implicit partial resync:

DBGRPC: CMD type=partial resync id=1 status=STARTED
DBGRPC: 1 STEP id=1 status=STARTED chid=default
DBGRPC: krmqgns: no work found for channel d1 (krmqgns)
DBGRPC: (krmqgns)
DBGRPC: EXITED krmqgns with status 1
DBGRPC: krmxcis: xc=436847736 chid=default calling pcicmp



10046 trace on the rman target default channel shows the target session is idle.
10046 on the rman catalog session shows the catalog is also idle.
The catalog database is accessed remotely via SQL through a firewall.
