Subject: 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?
