Your environment

• ROS Distro: [Noetic]
• OS Version: Ubuntu 20.04

Steps to reproduce

Steps can be reproduced by simplying running the default_warehouse_db.launch file inside your moveit_config folder generated by moveit. One also must set the "reset" argument inside the launch file to be true.

In addition to this scenario, I found that after I launch the MongoDB warehouse server and use the constraint from the warehouse to plan trajectories in moveit commander the same error can be seen in my moveit commander terminal window after I finish the trajectories.

*Note that everything works (eg. warehouse server, moveit planning), but this error just appears at the end of 1)launching mongodb warehouse server and 2)moveit commander planning.

Expected behaviour

It should just launch a warehouse database server using MongoDB without outputting any errors.

Actual behaviour

It prints out error

terminate called after throwing an instance of 'class_loader::LibraryUnloadException' what(): Attempt to unload library that class_loader is unaware of.
