<div dir="ltr" >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.</div>

<p><tt>Hi Frederick,</tt></p>
<p><tt>thanks for the answer! Unfortunately it seems not the case :(</tt></p>
<p><tt>[root@xbl-ces-4 ~]# netstat -ntp | grep "\:9094 .*CLOSE_WAIT" | wc -l<br>0</tt></p>
<p><tt>In 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:</tt></p>
