I have about 10 Win2008 SP2 Citrix Servers that show the above event logged in the System log prior to the servers becoming unusable and a hard boot is required.. The error relates to the Thumbnail Cache Out of Proc Server COM but I can't find out why it is happening and how I can resolve it. I have approx 10 users on each Citrix Server and their screen just locks up and can't do anything.. even logoff..! I would appreciate some help in resolving this one ASAP Mark
