I have the same behavior with that launch file on my system.

I have encountered deadlocks multiple times when launching
competition
in SubT. I've traced it down to the fact thatManagerPrivate::OnSigChild
uses non async-signal-safe functions which could cause deadlocks at startup when child processes exit. I've attached a simple.ign
file that reproduces the issue for me. Basically, it starts gazebo and a bunch ofsleep
commands with random amounts of sleep. The deadlock usually occurs deep inside malloc.
