Thank you, we will look into upgrading. -----Original Message----- From: Jan Friesse [mailto:jfriesse@xxxxxxxxxx] Sent: Wednesday, October 24, 2012 3:24 AM To: linux clustering Cc: Dryden, Tom Subject: Re: Set time on cluster We have support for monotonic timer since 0.80.6-33 (so RHEL >= 5.8). This should solve problems you are describing. What version are you using? If it's older then 0.80.6-33, try upgrade.
