Hi,
i get following Error in my XCP-ng Server (patched up-to-date).
It is a Pool of 8 Systems with shared NFS Storages.
It happened on different Hosts in the Pool. It seems it happens only when snapshots are running, but not every time.
In top you see:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
24093 root 20 0 67612 3856 184 R 100.0 0.0 3897:08 forkexecd
System is responsible via SSH, but not XOA / XCP-ng Center or xe commands in shell.
VMs are still running.
Has anyone seen this before?
