Hi all,
I'm currently trying to run a big simulation with traci using a cropped
version of the cologne scenario.
I'm outputting both the full output as well as the edge emissions data to
XML files.
After around 4000 (roughly half way) timesteps I am getting the error:
*double free or corruption (!prev)*
*Traceback (most recent call last):*
* File "mainScript.py", line 108, in <module>*
* main()*
* File "mainScript.py", line 92, in main*
* CHDurations, CHDistances = simulation("CH")*
* File "mainScript.py", line 53, in simulation*

_sendExact*
* raise FatalTraCIError("connection closed by SUMO")*
*traci.exceptions.FatalTraCIError: connection closed by SUMO*
It's running on Ubuntu with 8GB memory.
The full output XML file is at 3.4GB when it crashed which I feel may be a
cause.
Does anyone know what may be causing this error and how I can fix it?
Many thanks,
Toby
