    Description

      Build: 6.6.0-7834

      Test case:

      ./testrunner -i node.ini threads_to_use=8,rerun=False,skip_cleanup=True,get-cbcollect-info=False,skip_collections_cleanup=True -t Atomicity.doc_isolation.IsolationDocTest.test_staged_doc_read,nodes_init=2,num_items=1,replicas=1,transaction_timeout=30,transaction_commit=True,doc_op=create,operation=beforeAtrPending,GROUP=P0

      Cbcollect logs:
      https://cb-jira.s3.us-east-2.amazonaws.com/logs/transaction_crash/collectinfo-2020-06-24T195940-ns_1%4010.112.191.105.zip

      Scenario:

      • Two node cluster, Couchbase bucket with replica=1
      • Start transaction with expiry of 30 seconds. Forcefully fail the transaction during "beforeAtrPending" and retry

      Expected behavior:

      Failed transaction should succeed without any issues

      Service 'memcached' exited with status 134. Restarting. Messages:
