    Description

      Script to repo :

      guides/gradlew --refresh-dependencies testrunner -P jython=/opt/jython/bin/jython -P 'args=-i /tmp/testexec.27357.ini GROUP=P1,EXCLUDE_GROUP=MB_40967,get-cbcollect-info=False,bucket_storage=couchstore,upgrade_version=7.1.2-3378 -t epengine.basic_ops.basic_ops.test_store_value_del_updates_datatype,get-cbcollect-info=False,replicas=1,bucket_storage=couchstore,upgrade_version=7.1.2-3378,compression_mode=off,nodes_init=1,GROUP=P1,EXCLUDE_GROUP=MB_40967,bucket_size=100'

      Summary:
      While adding more documents and waiting for a particular document to get evicted , the following script starts returning a blank/null output .

      /opt/couchbase/bin/cbstats -u Administrator -p password localhost:11210 raw "_hash-dump 1005" | grep test_key

      Pre-eviction got the following output :

       SV @0x7f5d1a61c5d0 X.. .DR.Cm temp:    seq:3 rev:3 cas:1658129056992657408 key:"cid:0x0:test_key, size:9" exp:1658129056 age:1 fc:4 vallen:21 val age:1 :"\x00\x00\x00\x11\x00\x00\x00\r_key\x00"value"\x00"\n'

      Steps of the test:
      1. Creates a bucket with replica=1 on a single node cluster 172.23.120.206.
      2. Load sys-xattr for the document.
      3. Delete the document on active (system_xattr is still accessible)
      4. Loading docs to make the mentioned document a non-resident .
      (here while waiting for document to become non-resident got the mentioned issue )
