Memory consumption in tshark

[Dario Lombardo <lomato () gmail com>]

Hi list
I've run this command on a 10G pcap file.

./tshark -r traffic.all -Y "dns.qry.name.len > 50" -w longnames.pcap

Used memory grows continuously, up to over 3GB of ram. At this point my pc
goes thrashing and I must kill tshark.
That's not what I expected. I expected the memory to grow up to a certain
size, then stop, feeding the output file.
Any idea about what happens? Any suggestion on how to debug it?
Thanks
Dario.
