boost mutex exception thrown
I've created a Dockerfile that installs CUDA enabled opencv along with ros melodic. I've also set it up so it runs well with vscode using their remote development tools. I started working through an exercise: using this repository: https://github.com/udacity/simple_arm... simple_arm
My basic setup is here: https://github.com/jasonbeach/ros_uda....
I tried roslaunch simple_arm robot_spawn.launch however an exception is thrown:
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >'
what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument
Aborted (core dumped)

googling around most of the solutions indicated that rosconsole_bridge was to blame, however they all seem to reference ros kinetic and indicate the issue was fixed in newer versions of rosconsole_bridge.

roslaunch gazebo_ros empty_world.launch gives the same error. The other method suggested in these posts to trigger the exception in python actually don't throw the exception for me. i.e in python, this works without issue:
$ python
Python 2.7.17 (default, Jul 20 2020, 15:37:01)
[GCC 7.5.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.

<CDLL '/opt/ros/melodic/lib/liburdf.so', handle 557042927d30 at 7f36f80a6fd0>

python 3.6.9 works as well.
