Wireshark · Wireshark-dev: [Wireshark-dev] Memory consumption in tshark

[Dario Lombardo <lomato@xxxxxxxxx>]

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.
