Hi Harald,
Thank you for pointing that out. But how would I fix it, since
the xml-files are created and read by sumo.

Hi,
there seems to be memory leaks in the context of reading of
xml-files.
I have run the scenario twice with a simulation time of 5
resp. 10 seconds:
The output of valgrind (a memory checker under linux) shows
an increasing number of lost bytes:
valgrind28244.log (5 sceonds)

Attached is the modified py script and the output of valgrind
for the last run

Hi Abdullah,
I cannot see your .py file. Would you please send it as
a .txt file?

*Betreff:* [sumo-user] Using traci.simulation.loadState
increases memory usage
Hi,
I have noticed that if I use traci.simulation.loadState
multiple times then my memory usage increases
significantly. I have attached a simple code below,
where cars are being added to the network and after
every 5 seconds, a state is being saved and loaded back
up. If I do this multiple times, it increases my
memory usage. You can try the same code again by
commenting out line 47 and it will drastically reduce
the memory usage. Is there something I am doing wrong
and is there a way around this?
