Hi Michael,

I found on last nights training run a similar error occurred around 10mil steps, about 5hrs in. Would running my code in my Ubuntu dual boot as opposed to Windows stop this?

Kind regards,

Hi Jordan,
can you give more details on your system? Some systems limit the nummber
of open sockets or have a large delay on freeing a closed socket
(especially Windows). If this does not apply here I am afraid you can
only try to catch the exception and restart the sumo instance possibly
after some wait.

Best reagrds,
