logs are showing vmwgfx module is facing some issue to load. Along with this error server started showing more cpu average and extra memory consumption. Finally I had to reboot the server to clear it from tainted kernel state. This error is happening intermittently and I tried with Turn off APIC and ACPI but no luck.
