gzserver hang during shutdown #2079

Open osrf-migration opened 7 years ago

osrf-migration commented 7 years ago

Original report (archived issue) by Steve Peters (Bitbucket: Steven Peters, GitHub: scpeters).

Recently, gzserver has been less responsive to Ctrl+C. I recently attached to a hanging process (running test/worlds/revolute_joint_test.world) and got a backtrace showing that it is stuck in an infinite loop in Publisher::Fini:

Here's the full backtrace; maybe the TopicManager has already died?
