Have finally found the cause of the intermittent failures of our rman backup script and thought I should share it.

This backup script and many other scripts run ps -ef | grep pmon | grep $ORACLE_SID and expect to get a single line back. Just discovered today that AHF launches a background process that meets this criteria. When it is running, 2 rows are returned. It was an easy fix, but finding the cause when the AHF process runs so infrequently was a challenge.
