One of my servers is runing for 305 days. I Know that 8.0.2 and Centos 5.2 are old but the strategy is if is not broken don't fix it. This server is for Sametime (chat only), SMTP and some mail users using Notes. The webadmin message is from the server, and thanks to my datacenter too. I don't know if you can run a Windows box for a long time without reboots.
