I have two SharePoint 2010 WFE servers setup in a NLB Cluster in multicast mode. The servers are 2008 R2 running in a VMWare environment and both servers have only 1 NIC. Several times per week one of the servers goes into a "Converging" state and at which point some users are unable to access our SharePoint site. I have to reboot the server to get it to successfully converge again.
Microsoft has a hotfix available in the following KB: http://support.microsoft.com/kb/978943/en-us but I'm not sure if I should apply it because it specifically mentions that the server should be recording an entry in the System Event Log with Event ID: 19. However neither of my 2 servers are logging such an entry so not sure if this hotfix applies. Has anyone else seen this before or have any suggestions on other things to check or try?
Thank You
