test_no_conflicts_update_with_revs_limit failed while replicating - WebSocket connection closed by peer

Platform: Java WebService
CBL Version: Java 2.7.0-80
SG Version: SGW 2.7.0-163
SG Config: see attachment

Steps to Reproduce:
1. Have sg config with allow conflicts with some revs_limit
2. Create docs in CBL
3. Start a continous Replicator to have SG load all the docs. Verify if the no. of docs are same in both SG and CBL.
4. Update docs in CBL and also update docs through SG with number of times more than revs_limit. check the docs after replication become idle
5. Change the revs_limit less than actual revs limit
6. Restart sg
7. update doc 1 more time and let replication become idle

Actual Result:
