Hi, I have a situation that is extremely peculiar. My problem is easily described but not so easily diagnosed. When I login to my freebsd server from a remote host (on local network), after a random amount of time the connection just hangs -- unless I hit a key on the keyboard. The connection just freezes and sits there forever (or until the localhost resets the connection). For example, I have a telnet/ssh window open with top running to monitor load, the display eventually freezes. Now let's say a minute passes and then I hit a key on the server. Then the time displayed on top resumes exactly where it left off (so no packets seem to be accumulating). This happens whether telnetting, sshing, ftping, or any combination of these. The server does not even respond to pings and traceroutes! But somehow, hitting a key brings the machine "back to life". I am generally the only user of the machine. I have used netstat to check mbufs, lost packets, built custom kernels and played with sysctl settings, all of which yeild no success so I can't even think of any useful output to post! Just in case, I posted dmesg output to "www.marwanfayed.com/dmesg.out" PLEASE HELP! Thank you, --marwan ps. This is an old p200MMX w/ 128M ram running 4.8R. It used to run 4.5R quite happily until I upgraded by removing the stock hard drive so I can boot from a larger drive connected to a PCI ide card (at which point I installed 4.8R). Again, thanks. ******************************************************** "Theatre is not supposed to change the world, but it shows the world can change." --Ali Rafi'i ********************************************************
