I solved the problem! (after 10 days :-))
I had not used the "noutput_items" variable in the "general_work"
environment. so my blocks produced uncontrolled outputsamples :-(
Sorry about the confusion I produced.
Thanks to all who helped!

Hi Marcus

This is the workflow with the problem:
www.zhaw.ch/~hoim/Flow.py
With the command:
diff -u test1.txt test.txt | diffstat
after two runs I searched in the vector-sinks the differe

Can you attach a python script that demonstrates the problem?
I used this command:
sudo sysctl -w net.core.rmem_max=5000
Are you resizing the udp socket buffer?

Hi all
I think my program loses samples. If I choose for the input of my
flowgraph a file source with a throttle (Rate = 2 MSamples) and for the
output a vector sink, I see in the output vector that samples are loss
(every run differnet datas were loss). The CPU usage is only 40 Percent.
