Actually I am doing ROS_INFO_STREAM in one node three times. With
rostopic echo /rosout_agg I see all three messages. With my
subscriber I only see the last message, when calling spinOnce not
fast enough. So this can not be an issue of the queue filling up.<br>

Dear all,<br>
<br>
I am missing message when subscribing to /rosout<br>
<br>
_log_sub = _node.subscribe( "/rosout", 100,
&ROSHandler::logCallback,<br>
this );<br>
<br>
I do call ros::spinOnce() approximately every 20ms. When I
call spinOnce<br>
as fast as possible (in a loop) then no messages are lost. But
then my<br>
app needs 60% of the CPU so that is not really desirable.<br>

<div>If messages are coming in at > 50Hz, one would expect to
drop messages here, once the buffer of 100 fills up. No?
Just trying to establish if there is a bug here or not. I
suppose a way to check the size of the incoming queue would be
nice... there is a ticket on this already.</div>
