**Summary**
Gazebo will crash intermittently *when* I run it from roslaunch *in conjunction* with other ROS nodes
- If I roslaunch a .launch file that starts a .world file via gazebo_ros, Gazebo **does not** crash.
- However, my .launch file also contains a .urdf with plugins (that may use ROS and Gazebo messaging) and some other ROS nodes (containing SMACH finite state machines for example). In this case, Gazebo **does** crash *intermittently*, once every 2 - 10 launches.
- The crashing appears to become **more frequent** (a crash every 2-4 launches) as the number of ROS node's in the launch file goes up.
- My solution is to Ctrl-C the Terminal window and then simply roslaunch the .launch file again. Sometimes I have to repeat this process a couple times. Repeated Gazebo crashes also appear to become more frequent as the number of nodes I'm launching goes up.
- A weird trick, if I:
- $ roslaunch myfile.launch
- and then *immediately* click on my terminal window and *drag-it across my monitor.*
Gazebo will almost never crash. I have no idea why this works. I just know it does (for me).
**Error Message**
libGL error: failed to create drawable ...
[gazebo_gui-2] process has died ...

Also, I think there's a segmentation fault one, but I wasn't able to produce it on demand (as I said, the crashing seems somewhat random / non-deterministic)
**Graphics Card**
I have a non-NVIDIA Graphics Card:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Bonaire XTX [Radeon R7 260X/360]

Looking through the forums, there seem to be a number of related questions:

*Diagnosis:* ROS or Gazebo threading bug, race condition, graphics card
*Workaround:* Set gazebo_ros debug parameter to true, set node respawn="true" in .launch file

*Diagnosis:* gazebo_ros can't handle extra roslaunch __name and __log arguments
*Workaround:* start gazebo from separate terminal with rosrun

**Aside**
When I Ctrl-C the terminal window where I ran roslaunch, I usually get the following [gazebo-2] escalating to SIGTERM message:
[gazebo-2] escalating to SIGTERM
[rosout-1] killing on exit
Exception ignored in:
Traceback (most recent call last):
File "/usr/share/gdb/python/gdb/__init__.py", line 43, in flush
def flush(self):
KeyboardInterrupt

Including this in case it is relevant
**How to run Gazebo without crashing?**
Is there something obvious I'm missing. What's the best way for me to go about diagnosing/fixing this problem?
Thank you.
