Gazebo crashes (race condition?) [closed]

edit

Hi all,

I am currently using gazebo with a urdf of mine (under precise and hydro). It turns out to work well... once in every 5 or 6 sessions. With absolutely no change in the urdf or the config (I am repeatedly launching the same file from the same command line), I get repeated crashes and then once every 5 or 10 sessions (it varies) the simulation happens to work.

There are actually different error messages and which error message is displayed seems to be random depending on the session.

From the example error messages provided below, this problem could look like a race condition. Any idea of what's going on? Is this a known problem?

Thanks,

Antoine.
