(possibly install DDB so that it doesn't fully reboot, but stops in the debugger) I have a patch to fix the fin-wait-2 problem.. I have included it. (It was last tested in 3.2) What it does is allow probing of the client so that the client will send an RST if the session is really closed, and if no response for a while, it will time out. You need to enable it in the config file too julian On Mon, 25 Oct 1999, Min Wei (Exchange) wrote: > Hi. I have a situation where FreeBSD 3.2 reboots once a while (less than > every > 12 hours).
