Hello everyone,
I setup a new Proxmox box and was transferring data from another server (heavy network and disk load) when I lost all network connectivity. I could not ping the host or the guests. After about 30 minutes it came back alive!
In the logs I found this:
This repeats itself for about 30 minutes.
Do I have a ZFS (four SATA drives in ZFS RAID 10)? or RAM issue?
Thank you in advance for your help.
Kevin
