Comment # 5 on bug 12460 from 
I went back and double-checked everything.  Tried it with one NIC only
(disabled the second) and it does not fail.

The conditions to trigger the problem are:

1) two GBE NIC monitored simultaneously
2) auto-scroll disabled
3) Wireshark GUI window minimized
4) huge+fast burst of asynchronous DNS requests/responses
   balancing over the two paths as implemented by c-ares 1.11.0

An educated guess is that a mutex is needed somewhere, possibly in the analyzer
code that processes DNS traffic.
