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

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?
