Hello, After upgrading my site from 05.01.00 to 05.01.01, with no reported errors, I am getting errors in the event log pertaining to the BroadcastPollingCachingProvider -both a scheduler event failure and a general exception. Below are the event log error details: 8/8/2009 11:45:02 AM General Exception AssemblyVersion: 5.1.1; PortalID: -1; PortalName ...

I believe this issue is also causing high CPU utilization on the server. Can I simply disable the schedule for this without adverse side effects? Thanks and best regards, Ron
