Hi, I've just noticed two rospy.logdebug statement in cturtle action_server.py and simple_action_server.py: In action_server.py:314: rospy.logdebug("Status async"); In simple_action_server.py:306: rospy.logdebug("SAS: execute"); On my system, with my simple launch files and simple_action_server, these two are making my logfiles grow to infinity, and makes my action_server use 10% of my CPU while not doing anything. I've commented them out for now, but is there a smarter way? For information, I've also noticed that rosout is in general using around 10% of my CPU with a slow harddrive (within virtualbox), but that it goes down to 4-5% when putting the ROS_LOG_DIR in tmpfs. This might be significant for embedded system logging on a flash-drive. -- Dr. Cedric Pradalier http://www.asl.ethz.ch/people/cedricp
