glusterfsd: Memleak in glusterfsd process while brick mux is on
Problem: At the time of stopping the volume while brick multiplex is enabled memory is not cleanup from all server side xlators. Solution: To cleanup memory for all server side xlators call fini in glusterfs_handle_terminate after send GF_EVENT_CLEANUP notification to top xlator.
