Thanks Robert.

I guess the issue is resolved now after doing the mentioned step. Can you tell 
me how to verify the current tombstone counts in order to do a regular check?

Thanks

You stored a bunch of hints via hinted handoff. Then they got tombstoned.
 
2. How and where to monitor the current tombstone counts ?

3. done compaction, nodetool repair, increased the threshold count but still 
this tombstone is not getting resolved. How to resolve this issue?

Either major compact the hints columnfamily (might not be done by nodetool 
compact because it's system keyspace) or :

1) nodetool drain
2) stop node
3) delete all sstables in system/hintscolumnfamily
4) start node
5) repair

You should also figure out why you're storing so many hints, and stop doing so.
