argus error message

[MN]

Hi Carter - on Ubuntu 14.04.1 LTS, pcap 1.6.2, argus 3.0.8 (I've changed
control characters to ^x to prevent mailers from experiencing too much
anxiety):

This happens roughly ever 5 days on our three busiest Argus collectors.
It does not appear to affect flow collection.

Is it just some random TCP connection causing the problem?

Thanks,

ps: libpcap 1.3.0 and some versions of Argus do not work well - random
crashes every few days on 10gb connections.  We switched to 1.6.2 and
these problems went away.
