Looks like ganesha daemon is not closing socket fds for some reason. can you check the listener at service port number 39707 at the peer (ip address 129.129.99.247) above? "rpcinfo -p 129.129.99.247" may give us some info. If a service is restarted at the peer, it may not match though.
Regards, Malahal.

Hi Frederick,
thanks for the answer! Unfortunately it seems not the case :(
[root@xbl-ces-4 ~]# netstat -ntp | grep "\:9094 .*CLOSE_WAIT" | wc -l
0In our case, Zimon does not directly interact with Grafana over the bridge, but we have a small python script that (through Telegraf) polls the collector and ingest data into InfluxDB, which acts as data source for Grafana. An example of the opened port is:
tcp6 1 0 129.129.95.84:40038 129.129.99.247:39707 CLOSE_WAIT 39131/gpfs.ganesha.
We opened a PMR to check what's happening, let's see :) But possibly first thing to do is to disable IPv6
cheers
