I've encountered the same issue, however in my case it seem to have been caused by a bug in the kernel that was present between 4.4.0-58 - 4.4.0-63 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842), seeing how you are running 4.4.0-62 I would suggest upgrading and see if the error persists.

I did volume start force and now self-heal daemon is up on the node which was down.

But bitrot has triggered crawling process on all node now,  why was it crawling disk again?  if the process is running already.

Yes, I have enabled bitrot process and it's currently running signer process in some nodes.

Disabling and enabling bitrot doesn't makes difference it will start crawl process again right.
