WhatPulse bandwidth monitor causing crashes from memory allocation

WhatPulse bandwidth monitor causing crashes from memory allocation
Hi!

Every once in a while my WhatPulse client allocates an extreme amount of memory over the period of a minute, usually causing my computer to become unresponsive and freeze. It usually happens whenever I plug in my laptop to ethernet or use Docker, http://docker.com, which creates/uses a virtual network interface. I presume its something to do with the network part of WhatPulse based on the logs.

My computer is Xubuntu 14.04 x64, WhatPulse 2.5, with libpcap0.8. I run WhatPulse as root.

When running WhatPulse in a terminal window, stdout scrolls by fast as my RAM quickly fills up. The following from stdout is quickly repeated when the program is allocating memory:

11-04-2015 22:53:37.583 DEBUG PF-Ring thread stopped

Additionally, this is the log from app.log:
