Hi Guys,We've got a SharePoint environment consisting of a database server, application server and web server. The details are as below:Database Server===========SQL Standard 2008 SP1 x64Application Server============Windows Server 2008 R2SharePoint 2007 SP2 x64Central AdministrationIndex RoleWeb Server========Windows Server 2008 R2SharePoint 2007 SP2 x64Central AdministrationQuery RoleEverything functions correctly(e.g: search works, logging works) but we keep getting a recurring error on our application log as below (this is on our application server):Log Name: ApplicationSource: Office SharePoint ServerDate: 14/03/2010 10:40:12 PMEvent ID: 7082Task Category: Office Server Shared ServicesLevel: ErrorKeywords: ClassicUser: N/AComputer: serversp.bat.comDescription:An unexpected error occurred while refreshing the shared object manager cache. Reason: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)We've taken the steps below so far:Verified that farm account has the required privileges on all 3 servers.Executed stsadm updatefarmcredentials, although we did not change the accounts or passwords.Verified that SharePoint patch level is the same on both server.Verified that the required accounts do belong to the WSS_Admin_WPG and WSS_WPG groups.Verified that the SQL port is established and listening.Verified that there are no issues with connection between the 3 servers.We aren't very sure on what else we could be looking out for or checking? And the error continues to re-occur. Any suggestions and advice would be greatly appreciated.Thank You,Harish

Hi Ivan, Thanks for your help, by pointing us in the right direction we got this resolved. It was actually (wait for it) our VM ESX Server that was performing backups at the particular times that these errors get thrown. All ok now, cheers for the help. Kind Regards,Harish

Hi Harish, So are you saying it is okay for these errors to occur? Lavar
