Vmware ESXi (3.5) and RHEL (5.1) : Timekeeping Woes

I may have posted this here previously, and if not I know I spoke to Dell support, whom advised me to make sure that the "Synchronize guest time with host" was turned off.

Basically I have a RHEL5.1 server. It has the ntpd service running. This seems to stop every now and again. It took me quite some time to organize downtime on this VM, so I only got to turn off the option in setting last week.

Here is the log from messages:

Anyone have any ideas/suggestions?
