We have an NW 6.5 SP8 server that hangs without any abends. Clients are unable to connect to the server. There are no errors or abends on the console. This takes about 3-4 weeks to create this condition. There are no hints in the log files and no abends recorded. Rebooting the server clears up the problem for 3-4 weeks. There is plenty of disk space and ECC Dram installled. (I thought the server may be running low on memory with only 512MB, but the problem exists with 2GB of memory. The console is not locked up either. So, we just restart server and away we go. I appreciate any thoughts on what to look for on this box. Thanks,
