We are running ePO 4.0 Patch 2. The server has been running fine, however since installing P2 the 'Update Master Repository' and 'Schedule Replication' task either never completes or has a status of 'Waiting' even if no other task appears to be running.
I have created another task that performs the same thing (to eliminate the default ones), with the same result! The strange thing was one of the pulls actually pulled the new dats from McAfee but the replication task still stated that it was running!!
