Hi Jakub-


memory is not limited for user steve.(In reply to comment #3)

Hi Jakub-

I have plenty of memory:

[steve@nms231s1 freecolor]$ freecolor -b -o
             total       used       free     shared    buffers     cached
Mem:    3470589952  418836480 3051753472          0          0   32305152
Swap:            0  367149056 3927818240

I can reproduce the problem on another FreeBSD 9.0 machine, but it works fine
with the same capture file on Windwows XP (tshark 1.8.2 in both cases).

User 'steve' has no memory limits.

FreeBSD 'time' doesn't give any memory stats, but I ran it anyway:

[steve@nms231s1 ~]$ time -p tshark -n -r 20120214-BA_00001_20120214155239.pcap
-q -z io,stat,1

(process:65525): GLib-ERROR (recursed) **: gmem.c:240: failed to allocate 64
bytes
aborting...
Abort trap: 6 (core dumped)
real 34.29
user 3.24
sys 8.51

At the same time, I ran this in another console to give you an idea of the
memory usage:

SIZE is the total size of the process (text, data, and stack), RES is the
current amount of resident memory (both SIZE and RES are given in kilobytes)

I've uploaded the BA_00001_20120214155239.pcap file.
