Due to the nature of this problem, I can't do any tracing. I have noticed several times since upgrading to 4.2-RELEASE that the system will just "freeze". When this happens, you can still ping the IP of the machine on the local network, but you cannot get a telnet or ftp connection. You can not switch from X to a virtual terminal. The mouse pointer is non-responsive. The NUMLOCK key on the keyboard is non-responsive. However, something is still alive, as you can ping it. The only way out is a reboot. This is definitely "Un-FreeBSD-Like" behavior! I have been running FreeBSD for about 3 years on this machine, a P200MMX with 64 megs RAM and Tyan motherboard. The only clue I have is that I was attaching a 1.5 meg file in Netscape mail. I have also had this happen on certain web pages. Not ofter, but once or twice in a couple months. The other time I have had this happen was when writing to a bad floppy disk (bad sectors) using mtools. The file attachment caused a lot of disk activity and perhaps, given the floppy's causing the same of similar problem, this is I/O related? Just a wild guess. This could, of course, be a hardware problem that is creeping up, or a problem in XFree86 (I've never seen this in a virtual terminal). Anyone else seen this kind of behavior? I'm fairly certain that 4.1 did not do this. Does anyone have a suggestion for getting some useful information from the system. There is no crase, per se, so no crash dump. -Jim Durham To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
