A small slice of the large ping trace -- -qz icmp,srt works on this
Build Information:
1.10.0rc2 (SVN Rev 49526 from /trunk-1.10)
Windows 7 64bit

I'm using the following to calculate various ICMP stats:
tshark -r ping.pcap -qz icmp,srt
On some trace files, this works:
tshark -r pings-small.pcap -qz icmp,srt

[This requires ~18 minutes on my machine.]
And other times it does not:
tshark -r pings-big.pcap -qz icmp,srt
[This has been running for almost 5 hours on my machine and still hasn't
completed -- one of the cores on my CPU is pegged.]
pings-small.pcap and pings-middle.pcap are both slices taken from
pings-big.pcap
At the moment, I propose that size matters -- the larger the trace file, the
less likely it is to complete.
The traces files are visible at: https://vishnu.fhcrc.org/wireshark
I shall attempt to upload them as well.
