Can you please attach the core along with 't a a bt' output?
Comment 3 Atin Mukherjee 2017-06-26 02:59:04 EDT
I think this can be addressed as part of https://review.gluster.org/#/c/17601/

Mohit - thoughts?

There was a backtrace in /var/log/glusterfs/glusterd.log, which I have printed using my print-backtrace.sh to get the line numbers resolved. There's no core file that got dumped.

The resolved backtrace is available at comment #0 under Additional Info

Followed the steps mentioned by Milind, performed kill -9 on the brick process and glusterd and restarted glusterd on a node. No glusterd crash is seen. Hence marking it as verified.
