Changeset : 7640
Setup : 4 nodes cluster with PBE of 50k objects.SUSE 11.2 VM
Issue : Standby syncing is delayed with active controller, untill payloads join
the cluster.
Steps :
1. PBE is enabled on the setup and 50k DB is created earlier.
2. Started opensaf on all the nodes simultaneously.

3. Opensafd on SC-1 started at May 23 15:33:41.
4. Opensafd on PL-3 and PL-4 started at 15:33:42.
5. On SC-2, imm syncing started at 15:33:47 after the active controller and
payloads joined.
May 23 15:33:47 CONTROLLER-1 osafimmd[27837]: NO Successfully announced sync.
New ruling epoch:9
May 23 15:33:47 CONTROLLER-1 osafimmloadd: NO Sync starting
6. At 15:33:57, SC-2 joined the cluster successfully.
Because of this, time taken for standby to join during simultaneous startup
of all nodes have increased by sync time.
Value for IMMSV_NUM_NODES is default (5) and not changed.
