We already discard a great deal of state in (single-pass) tshark that we keep around in Wireshark (or two-pass tshark). We do need to keep some, though. It's only a bug if we're keeping more than we actually need, and that's not determinable from the information we have here. Dario, if you could get us a memory profile of tshark in this situation (through valgrind's massif tool, for example) that would help us debug further.
For sure. But I'd need exactly the commands to run and what I should give you back.
I dislike the idea of two-pass by default for exactly this reason: people expect tshark to be relatively state-less. This is already not the case, but it's a lot worse in two-pass mode. It might even make sense to add a --state-less flag to tshark that disables all options which require state. I don't know how feasible that would be however. Evan
FYI, 10G file is a giant DNS capture. Maybe the state kept in the queries (for conversations creation) triggers the memory consumption.
