Description
Regression after 6.0.0-1663 due to https://github.com/couchbase/goxdcr/commit/f33e79e97a6359cdf7b106d502d24fef2c951a10
Testcase finished without any data loss - rev ids were verified properly - test case fails while scanning for panic in logs
./testrunner -i /tmp/testexec.9460.ini -p stop-on-failure=False,fail_on_errors=1,get-cbcollect-info=True -t xdcr.rebalanceXDCR.Rebalance.async_rebalance_out_master,items=100000,rdirection=bidirection,ctopology=chain,update=C1-C2,delete=C1-C2,rebalance=C2,GROUP=P1
Above test case failed due to this panic in logs:
