Hi Luca,
It appears that input trace had some S1AP control information which nProbe was 
trying to decode as gtpv2
I think the probe is working as it should, since gtpv2 output information seems 
fine (as we were not expecting S1AP to be decoded)

Thanks and cheers

Remah,

Hi all,
Im getting a warning for missing decoder when running nProbe against sample 
gtpv2 trace
[gtpv2Plugin.c:614] WARNING: Missing decoder for GTP type: 0x4A [offset: 
18/0012][packet_id: 847063]

I did investigate input trace and reads fine with gtpv2 information
Any idea on this warning type?

Thanks and cheers
Remah
