Re: [sumo-user] Fatal Error during TRACI Running
We are aware of issues with the SSM device in regard to invalid output. However, we are not aware of crashing.
Any type of scenario where a crash can be reproduced would be helpful (the smaller the better).

regards,
Jakob

Hello Fan,

 

i guess maybe this come from the SSM-device. Because we are facing this issue as well. By using the SSM device, sometime sumo crash.

I don’t know the next step from sumo side about this specific topic with SSM device.

Jakob do we have a new update about this one ?

- I used version 1.1.0

- Yes，it always stop at similar step

- I tested the code and find out that if I delete all the SSM device related code，the simulation will run to the end without error.

 

I'll send you the code by tomorrow.

 

Really appreciate！

 

Best，

 

Fan

- what version of SUMO did you use?

- does the crash always happen at the same simulation step?

- what was the last python command executed before the crash? (the whole error trace would be useful)

- can you provide input files for reproducing the crash?

Hi,

 

I got a problem when I was running SUMO via TRACI controlled python code for some simple task. SUMO will be crushed at around 2460 simulation step (step length 0.1s), and the debugging program showed information as below:

 

Unhandled exception at 0x000000013f7ec750 in sumo-gui.exe: 0xC0000005: Access violation reading location 0x0000000000000070.

 

And address given by:

 

000000013F7EC750  mov         rax,qword ptr [rcx+70h]

 

If I use the SUMO configure file to start this simulation without TRACI, it is working well.

 

I cannot figure out why. Is anyone has experiments about this problem? 

 

Thanks.
