Hello, the problem persists in 19716. It is much less likely to occur, but it still happens. I run the same setup as last time and SUMO segfaults after ~600 seconds. It also gives same nonsense warning(s) prior to the segfault. Stdout:
Simulation started with time: 30000.00 Step #30497.00Warning: Vehicle 'h53498c1:1' performs emergency stop at the end of lane '-31232_1' because there is no connection to the next edge (decel=-22.99), time=30497.00. Step #30587.00 (992ms ~= 1.01*RT, ~5135.08UPS, vehicles TOT 68989 ACT 50 Segmentation fault (core dumped) ~Matej. On 12.1.2016 15:38, Matěj Kubička wrote: > Thank you for fixing it!
