Version-Release number of selected component (if applicable):

How reproducible:
Reporting the first occurrence.

Steps to Reproduce:
1) Create a distrbuted-replicate volume and start it.
2) cifs mount the volume on multiple clients.
3) From client-1 -> start creating files and from a diff terminal start continuous lookups.
   wait for some time and from client-2 -> Start creating hardlinks
4) Remove few bricks and wait till the remove-brick operation completes.

After completion of remove-brick, check rebalance logs and you will see above timer error messages.

Actual results:
Seeing timer errors in rebalance logs.

Expected results:
No timer error messages should come in rebalance logs.

On glusterfs version 3.12.2-7.el7rhgs.x86_64, followed the same steps as in the description and didn't see these timer errors in rebalance logs.

Moving this BZ to Verified.
