Observed behavior

Seeing stale sockets fds under brick process with brick-mux enabled. If I restart the glusterd2 service then the sockets count are getting increased with a count of number of volumes.

Right now on my system I have 100 pvc and I am seeing 419 brick sockets on a node.
[root@gluster-kube1-0 11720]# ll /proc/$(pgrep glusterfsd)/fd | wc -l
419

Expected/desired behavior

Stale socket fds should be cleaned.

Details on how to reproduce (minimal and precise)

  1. Create a 3 node gcs system using valgrind.
  2. Create 100 pvc.
  3. Enabled brick-mux.
  4. Stop/start the volume.
  5. Check the brick process sockets using "ll /proc/$(pgrep glusterfsd)/fd"
