Also, it has been commonplace for me to receive kernel messages of the
following nature (not sure why these occur):
Oct 14 04:39:14 /bsd: arpresolve: can't allocate llinfo
Oct 14 05:06:14 /bsd: arpresolve: can't allocate llinfo
Oct 14 05:33:14 /bsd: arpresolve: can't allocate llinfo
Oct 14 06:00:14 /bsd: arpresolve: can't allocate llinfo
Here is the entry for the fault traps:
Oct 14 08:47:03 /bsd: uvm_fault(0xe73c1008, 0x0, 0, 1) -> 1
Oct 14 08:47:14 /bsd: uvm_fault(0xe73c1008, 0x83384000, 0, 1) -> 1
>How-To-Repeat:
Essentially the system was being built as indicated above `make build';
particularly; cap_mkdb. Still the problem occured during the middle of
the execution of that command, and there is no clear reason why cap_mkdb
is the problem (although this was the only computationally-intensive task
running at the time).
>Fix:
After entering `continue' at the ddb prompt, the system continued operation;
however, I rebooted anyway.
