[bugzilla-daemon@xxxxxxxxxxxxx]

Bug ID	10394
Summary	Wireshark freezes under heavy load on single gigabit network.
Product	Wireshark
Version	1.12.0
Hardware	x86-64
OS	Windows 7
Status	UNCONFIRMED
Severity	Major
Priority	Low
Component	GTK+ UI
Assignee	bugzilla-admin@wireshark.org
Reporter	joel.rondeau@cognex.com

Build Information:
Version 1.12.0 (installed from file Wireshark-win64-1.12.0.exe). Already
uninstalled so I don't have the exact information. WinPcap is at 4.1.3.
--
Running Wireshark 1.12.0 on a Windows 7 x64 machine. I was testing my
application that sends data to/from tcp port 1069. I also had 2 lua scripts
running (one for tcp on 1069, the other for udp on 1069).

I was getting random freezes of the UI when sending large amounts of data.
Sometimes it would correct itself. Often, it would require killing the app and
restarting.

So my assumption was that one of my lua scripts was at fault. I removed both
lines from init.lua (leaving init.lua in it's installed state). The problem
remained.

As I didn't recall seeing this issue with wireshark 1.10.9, I downgraded.
Running 1.10.9, I am not having any issues, lua scripts reinstalled (and
unchanged).

The Windows machine is a Dell laptop connected to a docking station. The one
Ethernet adapter that is being used is on the docking station. Wireshark
currently recognizes 7 capture interfaces. 2 are VMware vitual ethernet
adapters, 3 are wireless (just 1 wireless adapter, which is turned off), 1 is a
Juniper virtual adapter. The last one is the Ethernet adapter on the dock.
(Intel 82579LM Gigabit Network Connection).

I am only capturing on the Intel interface. The amount of traffic on the other
interfaces is minimal.
