    Description

      Steps:

      1. Create a 9 node cluster
      2. Create a 5 node XDCR remote cluster
      3. Create required buckets and 10 collections.
      4. Create required buckets and 10 collections on XDCR remote.
      5. Create 1000000 items/collection with durability majority
      6. Update 1000000 keys to create 50 percent fragmentation
      7. Create new 1000000 items/collection with durability majority
      8. Update new 1000000 keys to create 50 percent fragmentation
      9. Start a CRUD data load asynchronously.
      10. Rebalance in with Loading of docs. Crash and resume rebalance at 20%, 40%, 60%, 80%.
      11. Crash Magma/memc on source cluster 20 times with Loading of docs
      12. Rebalance Out with Loading of docs. Crash and resume rebalance at 20%, 40%, 60%, 80%.
      13. XDCR replication seems to be stuck. Since 30 mins 64.005M mutations remaining
      14. Also, because there were continuous CRUD going on the in the source cluster items in destination cluster are more than in source. Not sure if this is expected?

      QE Test

      git fetch "http://review.couchbase.org/TAF" refs/changes/06/163706/1 && git checkout FETCH_HEAD
      guides/gradlew --refresh-dependencies testrunner -P jython=/opt/jython/bin/jython -P 'args=-i /tmp/magma_temp_job4.ini -p bucket_storage=magma,bucket_eviction_policy=fullEviction,rerun=False,iterations=2,sdk_timeout=60,log_level=debug,infra_log_level=debug,skip_cleanup=True -t aGoodDoctor.Hospital.Murphy.SystemTestMagma,nodes_init=9,graceful=True,skip_cleanup=True,num_items=1000000,num_buckets=1,bucket_names=GleamBook,doc_size=1024,key_size=18,assert_crashes_on_load=True,num_collections=10,xdcr_collections=10,maxttl=10,num_indexes=20,pc=10,xdcr_remote_nodes=5,index_nodes=0,query_nodes=0,cbas_nodes=0,fts_nodes=0,ops_rate=50000,doc_ops=create:update:delete:read,durability=Majority,crashes=10 -m rest'
      

      I have this observation with XDCR that the RAM usage on the source/Dstn cluster is always very high while there is no mutation on the source cluster and just XDCR is runing.

            I would say that the number of mutations you're seeing is probably due to the inability to start backfill pipelines due to a few issues. I'll link them in this MB.

            https://issues.couchbase.com/browse/MB-49024 resolved will help the situation where backfill pipeline couldn't start and keep restarting.
            You can always try to turn off p2p like I mentioned below.

            It is working fine without turning p2p off on the recent volume runs. Last one is on 2305 build where replication completed properly at 4TB src : 400M dstn cluster.
