Wireshark · Wireshark-dev: [Wireshark-dev] Why am I getting a BoundsError?

[Andrew Schweitzer <a.schweitzer.grps@xxxxxxxxx>]

I'm writing a dissector for a proprietary protocol and using 
tcp_dissect_pdus. Our packets can be 2k, and sometimes I seem to get 
incorrectly parsed messages in the gui. I see the text in the gui 
"Packet size limited during capture".

I found this in packet-frame.c, and apparently I'm getting a 
"BoundsError", possibly because my "snapshot length too short".

Any idea what's going on here? Is there something I can do to fix it? 
Either in code or in settings?

Thanks

Andy
