system not reachable => avahi-daemon[514]: Withdrawing address record ?

Hello,

I have been using OMV in version 4 for quite some time without any downtime.

This week I updated to v5 and the update process as desribed here went really smoothly.

However, what I'm observing now is that after roughly 24h the system is not reachable via network anymore (but still seems to be running).

The syslog at the relevant down-time moment reveals

Jun 4 15:46:36 serv01 avahi-daemon[538]: Withdrawing address record for 192.168.xxx.xxx on enp3s0.
Jun 4 15:46:36 serv01 avahi-daemon[538]: Leaving mDNS multicast group on interface enp3s0.IPv4 with address 192.168.xxx.xxx.
Jun 4 15:46:36 serv01 avahi-daemon[538]: Interface enp3s0.IPv4 no longer relevant for mDNS.

or

Jun 5 16:30:11 serv01 avahi-daemon[514]: Withdrawing address record for 192.168.xxx.xxx on enp3s0.
Jun 5 16:30:11 serv01 avahi-daemon[514]: Leaving mDNS multicast group on interface enp3s0.IPv4 with address 192.168.xxx.xxx.
Jun 5 16:30:11 serv01 avahi-daemon[514]: Interface enp3s0.IPv4 no longer relevant for mDNS

Does anyone have encountered this as well and/or does anyone have a suggestion where to look further or what to do here?

Thanks a lot for any support & kind regards - tullsta

Hello,

the effect described above occurred again 24h after a reboot.

After giving the OMV-server a static IP address, the server access survived now more than 24h - hope it stayed like this

Comments/explanation welcome!

Kind regards - tullsta
