rosmaster doesn't close sockets properly, hangs #495
Description
Steps to reproduce:
- Start
roscore - Launch rosout repeatedly:
while :; do rosrun rosout rosout; done - Monitor CLOSE_WAIT sockets:
lsof | grep rosmaster | grep -c CLOSE_WAIT
The number of sockets keeps steadily climbing until the open file limit is hit. rosmaster then becomes unresponsive (e.g. rostopic list or rosnode list both just hang) and starts consuming 100% CPU.
Versions:
Ubuntu 12.04.5 LTS
ros-hydro-desktop-full 1.0.2-0precise-20140807-2038-+0000
Background:
While starting rosout in a loop isn't the most sensible thing, it's just the minimal test case to reproduce this. Trying "rosnode list" or "rostopic list" doesn't leak sockets in the same way.
I've had a few instances of this happening and it probably hasn't been rosout (but due to other pressures I haven't had the time to figure out the flaky component)
