Hi guys, we are facing an curios problem where after we cleaned (Delete query) one huge table (28gb) we have a different DataMemory usage status between Data nodes:

ndb_mgm> all report memoryusage
Connected to Management Server at: localhost:1186
Node 3: Data usage is 67%(1541828 32K pages of total 2293760)
Node 3: Index usage is 21%(418587 8K pages of total 1966464)
Node 4: Data usage is 51%(1181913 32K pages of total 2293760)
Node 4: Index usage is 23%(461147 8K pages of total 1966464)

I didn't mention IndexMemory on the subject because I believe it is related.

The data seems consistent. We already did restart Node 3 with and without --initial. My next step might be remove it and re-add it with an different IP.

Do you guys have any idea of what happened and what to do to resolve it?
