[NFS-Ganesha-Support] Extremely unstable export

Hi. I recently did an update of our system and my NFS export has become extremely unstable. It will work for a few minutes, but then stopsThe ganesha.log file shows the following messages: ganesha.nfsd-43423[dbus_heartbeat] nfs_health :DBUS :WARN :Health status is unhealthy. enq new: 116158, old: 116157; deq new: 116148, old: 116148 When I do a systemctl status -l I see: rpc-clnt-ping.c:162:rpc_clnt_ping_timer_expired For each of the servers in the set, but a ping of the server responds right away. I haven't been able to find online an explanation of the problem. Could anyone help ? Here are the current software version numbers: O/S: CentOS Linux release 7.6.1810 glusterfs: 5.8-1.el7 nfs-ganesha: 2.7.6-1.el7 Thanks, -- Valerio Luccio (212) 998-8736 Center for Brain Imaging 4 Washington Place, Room 157 New York University New York, NY 10003 "In an open world, who needs windows or gates ?"
