I have a Domino Release 6.5.4FP2 on a Winodws 2003 X260 IBM Server Mcafee Antivirus. It seems every 6 to 7 days we start getting routing and replication issues with remote Domino Servers running 6.5.1 on Windows 2000 Servers. I have restarted the routing and forced routing to the first 2 servers that start to show that mail is not being delivered. The remote servers still seem to be able to send mail through the main Domino server in question. I have found it difficult to find any answers on this 6 to 7 day cycle when the routing and replication gradually seems to fail across all the domino servers. Rebooting the server fixes it again for another week. Restarting the domino server does not help. I am getting warnings that the Task Replicator on server is no longer responding, Probable Cause: Task never update it's timestamp. Any ideas would be welcome.
