I have a Dell OptiPlex GXi (Pentium-133 with 96MB RAM) running
3-STABLE (from last night) which is used to simulate a WAN (using
dummynet). Under normal operation, it hangs about every 2 weeks,
but I can make it happen in about 15 minutes by loading up the
box. When it hangs, it does a good job - no response to the
network, keyboard or even NMI. These crashes are becoming quite
embarrassing. Does anyone have any suggestions on how to locate
and fix the problem?
Following are dmesg output, as well as the ipfw and natd files
(addresses have been changed).
