>Description:

netbsd drops me into ddb every few hours with a page fault trap. ran fine
for a week when it had no network load. after moving dhcpd and named services
to the box it now crashes every few hours.

this is entirely RC3 kernel and userland, no compat stuff all obtained from
ftp.netbsd.org.

please let me know what other info to provide on the next crash and how to
get it.

thanks
