I posted this a while back but never saw any kind of resolution. I just tried the latest 10.9 release and it's still a problem.

This problem seems to have been introduced somewhere around ethereal 9.4

I've noticed a problem in at least the last two releases 10.5 & 10.6 of Ethereal that did not occur in earlier circa 9.1? versions.


Do a "Follow TCP Stream", after the default display in ASCII comes up I then select any other format, (typically Hex). If the stream is relatively large, the redisplay in the nex format takes unusually long to forever.

In my largest case, I have 10 meg stream. "Follow TCP Stream" takes approximately 90 seconds to produce the ASCII stream. Selecting "Hex" results in the CPU pegging at 100% and even after 2 hours never produced a display.

This same data set did not have this problem with versions of ethereal from about a year ago.

My main machine is runnning RedHat 9.0, 3.0 GHz, with 1 GB of ram.


I'have identical results on a laptop with Fedora Core 2, 1.6 GHz, 1 GB ram.
