NetBSD bacon 1.4.1 NetBSD 1.4.1 (GENERIC_CGD) #16: Thu Sep 16 18:52:54 PDT 1999     cgd@bacon.:/a/src/src-1-4-branch/sys/arch/i386/compile/GENERIC_CGD i386
i386 kernel crashed while compiling kde.  looks like pkgsrc went
nuts spawning recursive shells/sub-makes, and the system ran
out of processes according to the dmesg output.  Then it trapped,
and dumped core.

dmesg output from right before death:

proc: table is full
proc: table is full
proc: table is full
fatal page fault in supervisor mode
trap type 6 code 0 eip f0233c98 cs 8 eflags 10286 cr2 fccd2068 cpl 0
panic: trap
syncing disks... 24 24 18 2 done

that eip is in gdt_compact().

Unknown.  Run out of processes on an i386 system?  I'm gonna try
it again, with a kernel from the latest 1.4-branch sources.

More details available upon request, including kcore to trustable
hackers, if need be.
