Lee Ann -- Thanks for your bug report.
I'm not able to find a call to NBC_Schedule_request() in ompi_coll_libnbc_iallreduce(). I see 2 calls to NBC_Schedule_request() in ompi/mca/coll/libnbc/nbc_iallreduce.c, but they are in different functions. Can you clarify exactly which one(s) you're referring to?
