sniffing hangs / too fast sim? / parsing problem?

Hey guys, this problem has been around for ages (from my perspective) .. and I don't seem to understand if it's a SW issue or a HW issue. I start the ./simtrace .. and then insert the SIM into the phone (or vice versa), boot up the phone and start sniffing (log below). It works for a second or two and then the stuff get broken into weird parts .. I could probably fix that in apdu_split.c but the other issue is that it stops sniffing completely at that point for some reason. Any idea why that happens? Thanks!
