Collvoid Package : ORCA algorithm not working

edit

Hi ! While using the Collvoid Package, I tried to use the ORCA algorithm by changing the "ORCA" parameter in collvoid_config.yaml to "true". But after running the launch file sim_created.launch in Collvoid_stage, I get the following error

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
