    Description

      Steps:
      1. create a single node cluster 172.23.104.107
      2. create a bucket with magma as storage and 256 MB of RAM
      3. performing CRUD operation using memcached direct client connections

      when running the exact same test code with 7.2.4-7014 the test is working , main concern is the difference in behaviour from 7.2.4 as the test code and bucket configuration is exactly the same but test always fails for 7.6.0

      7.2.4

       failure is seen from around the timestamp
