this issue occurred a month ago also prior to that and it
happen again yesterday
what our client does is restart the VM to get it back on
they already migrated this VM to a new server SANGFOR HCI
but the issue still persist
without any details its hard to know. Are there any alarms regarding CPU utilization / Disk usage? Is the hypervisor overprovisioned? Also, this is not a zone director but rather smartzone. And if you have support issues, you should have a support contract and open a ticket. The forum is mostly run by other users who volunteer their time.
Not sure which hypervisor you're using ... But at least it doesn't look like hyperv / azure / aws / google / VMware. Also, for some reason you're emulating two numa nodes (2 sockets / 4 cores per socket). Shouldn't make a difference but weird it got configured like that.
