Error: "icsim" is not resonding

I could install and create all required files, and after that I ran it with "./icsim vcan0" command. A few seconds later I got this error message:

I tried also with clean command to delete all created files and then recreate them, however the same error message popped up.
Do you know what could cause this failure?

It's only a bug, I figure it out. When there's a traffic on the vcan0, it disappear.
