[ARGUS] Segmentation Fault with 2.0.6rc2 on FreeBSD 4.9-RELEASE

[eric]

I have argus running under daemontools on freebsd 4.9-RELEASE. I've
done to this to take care of argus' falling down when we are pushing
large amounts of traffic through the network (140Mbps).

However, a corefile turns up the following...

GNU gdb 4.18 (FreeBSD)
[...]
Core was generated by `argus'.
Program terminated with signal 11, Segmentation fault.

And the error message is...

argus[16318]: ArgusProcessPacket () ArgusWriteOutSocket Failed 
              to Multiplexor. Shuting Down

It can't be a bottleneck to the disks; iostat shows only about
10MB/sec are being written to disk during high usage.

Any thoughts are appreciated!
