new version of argus-2.0.0l

[Peter Van Epp]

	While the new 2.0.0l works fine on Solaris at 1 meg, at 100 megs it
hangs pretty consistantly when HUPed (I only got one successful HUP in about 
10 tries, and that one worse luck, had a previous no data HUP in the argus log
so the size is a little big, but ra appears to have captured all the packets
successfully at 100 (or more correctly 95 or 96 megabits per second, however
fast tcpreplay could get the data there). 
	There looks to be a loop in the first task on the HUP note the CPU time
climbing:

skaha# !312
bin/argus_dlpi -i qfe0 -w argus.log &
[1] 5649
skaha# kill -HUP 5649
skaha# 

skaha# !ps
ps -ef | grep argus
    root  5650  5649  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5651  5650  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5653   534  0 16:34:41 pts/1    0:00 grep argus
    root  5649   534 29 16:34:08 pts/1    0:18 bin/argus_dlpi -i qfe0 -w argus.log
skaha# !!
ps -ef | grep argus
    root  5655   534  0 16:34:48 pts/1    0:00 grep argus
    root  5650  5649  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5651  5650  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5649   534 35 16:34:08 pts/1    0:24 bin/argus_dlpi -i qfe0 -w argus.log

a while later:

skaha# !ps
ps -ef | grep argus
    root  5650  5649  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5651  5650  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5657   534  0 16:40:04 pts/1    0:00 grep argus
    root  5649   534 50 16:34:08 pts/1    5:40 bin/argus_dlpi -i qfe0 -w argus.log

	Then a HUP again:

skaha# !333
kill -HUP 5649
skaha# 
[1]    Hangup               bin/argus_dlpi -i qfe0 -w argus.log
skaha# !ps
ps -ef | grep argus
    root  5650     1  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5651  5650  0 16:34:08 pts/1    0:00 bin/argus_dlpi -i qfe0 -w argus.log
    root  5659   534  0 16:40:35 pts/1    0:00 grep argus
skaha# 

	Now I have to kill -9 the last two tasks and the argus.log file isn't
complete. If you have suggestions on what we can do to debug this it looks
easily reproducable :-)
