[Carter Bullard]

Hey Peter,
   Found a potential spot, so I put some protection around it.
   Fix is in 'X', so if it happens again, please send me some mail.

Subject: core dump while killing argus


	I just killed an argus_bpf (2.0.0W) on FreeBSD 4.2-RELEASE:


test4# ps auxw | grep argus
root     166  0.0  2.1  2428 1288  p0  S     9:36PM   0:00.57 argus_bpf
-w argus
.log
root     167  0.0  1.6  2136  976  p0  S     9:36PM   0:00.27 argus_bpf
-w argus
.log
root     168  0.0  1.8  2272 1112  p0  S     9:36PM   0:00.20 argus_bpf
-w argus
.log
test4# kill -HUP 166
test4# !ps
ps auxw | grep argus
[1]  + Done                          argus_bpf -w argus.log
test4# ls
.cshrc          .login_conf     .profile        argus.log
.history        .mail_aliases   .rhosts         argus_bpf.core
.login          .mailrc         .shrc

	And got a core (although it looks to have shut down correctly):

test4# gdb argus_bpf argus_bpf.core
