Don't think too hard regarding zeromq, as zeromq is allowed to drop messages under certain circumstances. If you read the 0MQ Guide, you'll find that with PUB/SUB you're pretty much guaranteed to lose the first few messages, if no subscribers have connected yet. http://zguide.zeromq.org/page:all#toc114 There might be a way to craft better zeromq tests in gnuradio, but failures from the current gnuradio zeromq tests can be false positives. -Andy > Any clues for how to debug these failures?
