3284399 - Lock entry is getting lost after ASCS failover when using Enqueue Server 2

Symptom

The system has an ASCS instance running with the Standalone Enqueue Server 2 (ENSAv2) in a HA (High Availability) / cluster environment.

The system also has an ERS instance running the Enqueue Replicator 2 (ER2).

Even so, the locks are lost if there is a failover of the ASCS.

At the transaction SMENQ -> Server Administration, the "Replication" state has yellow background with text "Active (update pending)".

The following (or similar) entries are seen at the ENSAv2 trace file (dev_enq_server):

[date and time] [Thr nnn] EnqReplica: replication enabled
[date and time] [Thr nnn] EnqReplManager: connecting ER2 on hostname:sapdpXX
[date and time] [Thr nnn] EnqReplManager: starting master thread
[date and time] [Thr nnn] ***LOG GOD=> SystemLog, ReplicaSuspended () [EnqSystemLog 86]
[date and time] [Thr nnn] EnqReplManager: repairing replication
[date and time] [Thr nnn] EnqReplManager: master channel NOT connected (8.1 seconds)
