Are you sure your swapdevice is configured and works (swapinfo(1)) Device 1K-blocks Used Avail Capacity Type /dev/sd0s2b 98304 9376 88864 10% Interleaved > 2. Can you reproduce it ? Alas, no. I didn't write down where I set the breakpoint. I tried gdb on calctool again with a few different breakpoints and couldn't reproduce the freeze. I also wrote a test program called memhog that allocates however many megabytes you tell it to from the command line. When the system runs out of RAM you can see the swap disk activity. This test program runs fine. When run as root in single-user mode it is able to allocate 63 MB. > 3.

Even if I could reproduce the freeze this would not do any good. As I said, when the kernel freezes the keyboard is dead. Even CTL-ALT-DEL doesn't work. It would be impossible to get into the debugger. Since I can't reproduce this myself I certainly can't tell you how to reproduce it. I guess there is nothing more you can do about this problem at this time. ------- End of Forwarded Message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
