snmptrapd forwarding twice every received trap

I am running 14.04 server and am I trying to log traps received from an external source

at the same time I need to forward these traps to another server.

External Source -----> Ubuntu 14.04 ------------>Second server

I works usign snmptrapd,

NET-SNMP Version: 5.7.2
Web: http://www.net-snmp.org/
Email: <email address hidden>

however, every received trap is re-sent twice from the Ubuntu server

External Source ---1x--> Ubuntu 14.04 -----2x----->Second server

I have confirmed this with a sniffer on both the ubuntu server and the external server

My config in the snmptrapd.conf file is this:

authCommunity log,net community1
forward default 201.103.60.138
format2 %V\n%Date:%h:%j:%k-%l/%m/%y\n%v\n--------------\n

I have tried several tweeks but this seems to be a bug

The debuging shows also this behaviour
