All of the blocking calls in this block should be interruptible by boost thread interrupt (when stop is called). Are you able to rebuild or debug this? I suspect that one of the work calls is blocking and not interrupting... https://github.com/guruofquality/grextras/blob/master/lib/stream_selector.cc Can I ask what version of boost. To make sure this isnt the issue: http://gnuradio.org/redmine/issues/477 -josh ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I'm really not sure why, but I would like to fix the issue. Can you narrow down the issue to a subset of the blocks that cause a problem? code snippet? Is there a reason you think its the stream selector blocks (for example)? -josh > > > ___ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
