Description
Noted on MB-49019 memory stat issue
ep_mem_used_primary: 985984

ep_mem_used_secondary: 0

mem_used: 4273836803

Steps:
- Create a 9 node cluster
- Create a 5 node XDCR remote cluster
- Create required buckets and 10 collections.
- Create required buckets and 10 collections on XDCR remote.
- Create 1000000 items/collection with durability majority
- Update 1000000 keys to create 50 percent fragmentation
- Create new 1000000 items/collection with durability majority
- Update new 1000000 keys to create 50 percent fragmentation
- Start a CRUD data load asynchronously.
- Rebalance in with Loading of docs. Crash and resume rebalance at 20%, 40%, 60%, 80%.
- Crash Magma/memc on source cluster 20 times with Loading of docs
- Rebalance Out with Loading of docs. Crash and resume rebalance at 20%, 40%, 60%, 80%.
- XDCR replication seems to be stuck. Since 30 mins 64.005M mutations remaining
- 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?

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.
