[Bro] worker dies out of memory

[Aaron Gee-Clough]

All,

I've had this problem pop up twice in the past couple weeks, where I
restart bro & learn that one of the workers has crashed. The message
that comes back in the crash report is:

listening on dag0:32, capture length 8192 bytes

This is running on Ubuntu 12.04, bro 2.4, linux kernel 3.2.0-70, with
pcap compiled to use the Endace dag card, and bro compiled to use google
perftools. The box has 256GB of RAM.

Has anyone else seen this?

Thanks.
