[Discuss-gnuradio] messages get lost randomly |

Hi Guys,
I am using the messaging support of basic_block registering the
message queue with message_port_register_in and removed the obtained
messages with delete_head_blocking. This block is producing streams
and everything seems to work fine as long as I consume the messages
fast enough. However, if I put a throttle block after my stream
producing block, then messages get lost.
The producer generates 10000 messages with message_port_pub, but the
consumer does not receive all of those messages. I intentionally wait
500 ms on the producer for the consumer to be started (otherwise the
consumer might not get registered in time). So I have verified that
the problem is not in my code, but somewhere the messages get lost.
As far as I see in the basic_block code these message queues are not
regular msg_queue objects but std::deque objects protected by locks. I
do not see how messages could get lost. Any ideas?
Miklos
