Red Hat Enterprise Linux 6 guest running on VMware® Virtual Platform hangs while creating snapshots.

Solution Verified - Updated 2018-08-02T06:37:58+00:00 -

Issue

Red Hat Enterprise Linux 6 guest running on VMware® Virtual Platform hangs while cloning.
Since kernel version "2.6.32-358.6.2.el6.x86_64" our RHEL-6 machines have become unresponsive during very high loads on our storage. They hang one by one exactly ( with an accuracy to the second ) when the VMware® "create virtual machine snapshot" task starts creating the snapshots of each of them. We create snapshots in groups of 50-70 vm's simultaneously.

Environment

Red Hat Enterprise Linux 6
kernel-2.6.32-358.11.1.el6
VMware® ESXi Virtual Platform
VMware® vCenter Server
VMware® "vmsync" module
