VM Server going to hung state due to snapshot backup failed

By WireINPUT -
Guest OS VM sessions going into hung state or unresponsive state while taking snapshot backups. The reason being, while taking snapshot backups, if any more activities planned like running some batch scripts that might cause CPU spike.

This leads to more load on the VM session, the assigned resources are not available or in some cases, the data store got filled out fast.

In this scenario, we will have stop the VM snapshot backup and reboot the server and check the logs what is the reason the server went into hung state.

If the same issue getting repeated, VMware admins can do is, when you found the VM session in unresponsive state, move the VM into suspend mode and download the logs. Later can do the investigation if needed.
