Linux – VMware snapshot + An error occurred while saving the snapshot msg.snap-hot error

linuxsnapshotvmware-esxi

I am using VMware version 5.5 (that manage 57 different VM Linux machines –red-hat version 6 until 7 )
In the VSphere Client (tasks and event), I saw the following error: (on Linux machine name – Korfo_prod43 )

An error occurred while saving the snapshot msg.snap-hot error –Q- UIESCINGERROR

And when I try to log via SSH to the Linux machine, I notice that Linux machine is Hung (freeze state), so only reboot was needed to start up again the machine

In order to find a resolution for the snapshot problem,

I find the following resolution but not sure if this resolution is completely fit for my problem?

I have run into this issue in the past. Updating to the patches recommended in the KB fixed the issue.

An alternative workaround, which I used until I was able to patch, is to edit /etc/vmware-tools/tools.conf, and add these lines:

[vmbackup]
enableSyncDriver = false

This will cause the snapshot to only run a sync operation before the snapshot, and to not run a quiesce on the filesystem.
