Currently,
getLatestProductcallsqueue_.waitDequeTimedto retrieve a package from the queue, which means that it always retrieves the oldest package from the queue (when the queue contains more than one package). The additional packages remain in the queue, which can cause the queue to fill up over time and lead toPipeline producer overflowed!errors:Universal_Robots_Client_Library/include/ur_client_library/comm/pipeline.h
