[ros-users] topic queue

Dear all,

I am missing message when subscribing to /rosout

_log_sub = _node.subscribe( "/rosout", 100, &ROSHandler::logCallback,
this );

I do call ros::spinOnce() approximately every 20ms. When I call spinOnce
as fast as possible (in a loop) then no messages are lost. But then my
app needs 60% of the CPU so that is not really desirable.

A
rostopic echo /rosout
catches all messages.

Any ideas?
Regards Christian
