Unexpected output before "sync"

When I run "sim sync numrel02", I see unexpected output before sim starts. I refer to the lines stating "executing command: /bin/bash ps". These lines should probably not be output.

$ ./bin/sim sync numrel02 DEBUG: Simfactory command: ./bin/../simfactory/lib/sim.py "sync" "numrel02" DEBUG: Version 1125:1135 The Simulation Factory: Manage Cactus simulations
