Hi Matei,
When I run
roslaunch pr2_tabletop_manipulation_launch pr2_tabletop_manipulation.launch
even though I changed the use_database parameter to false, this error still
pops up each time during the launch.
[ERROR] [674.702000000]: Database connection failed with error message:
could not translate host name "wgs36" to address: Name or service not known
[ERROR] [674.702000000]: Failed to open model database on host wgs36, port
5432, user willow with password willow, database models
[FATAL] [674.702000000]: BREAKPOINT HIT
file =
/home/aleeper/ros/overlays/tabletop_object_perception/tabletop_collision_map_processing/nodes/tabletop_collision_map_processing_node.cpp
line=173
[tabletop_collision_map_processing-36] process has died [pid 31557, exit
code -5].
log files:
/home/aleeper/.ros/log/9acfc274-905b-11df-8f09-002354971365/tabletop_collision_map_processing-36*.log
And a result, when I try to run the pick_and_place keyboard demo it gets
stuck here:
[ INFO] [713.141000000]: waitForService: Service
[/tabletop_collision_map_processing/tabletop_collision_map_processing] has
not been advertised, waiting...
Do some of the other nodes also need to know that the database is not being
used?
Thanks,
