When I control-c a roslaunch command, each node is terminated first with sig-ints. If the node fails to die after 10 seconds, sig-int is escalated to sig-term. Is there a way to stop or delay this escalation from happening?

This is useful when debugging examples like this one.

Right now this delay is not configurable, so changing this behavior means editing pmon.py in roslaunch directly. It would be a good future enhancement to make roslaunch more configurable.

pmon.py will work for now. Thanks.

looks like that's nodeprocess.py rather than pymon.py.

For kinetic this can be found in:

/opt/ros/kinetic/lib/python2.7/dist-packages/roslaunch

In the file nodeprocess.py there will be 2 variables on line 57 and 58.

_TIMEOUT_SIGINT = 15.0 #seconds

_TIMEOUT_SIGTERM = 2.0 #seconds

change these if needed
