[Discuss-gnuradio] gr::log :WARN: udp_source0 - Too much data; dropping packet.

Hi,
I am writing a code where data is psk modulated in a host and then the 
modulated psk symbols are sent over udp to  a remote host where a demodulator 
is setting.
I am having troubles getting it to work.
I have the following warning message filling the console.

"gr::log :WARN: udp_source0 - Too much data; dropping packet."

It looks there is a flow control problem. However, I tried to increase the 
buffer size of the source udp but I still have the same problem.

The code is very simple. It is: 
in host 1:  signal source >> packet encoder >> DPSK modulator >> udp sink

in host 2: udp source >> DPSK demodulator >> packet decoder >> GUI time sink
