pybullet is automatically killed after long time of running

[Xunmenggod]

Hi, I am using the pybullet simulation to create a gym environment for robot manipulation. And I tried to use stable baseline3 rl algorithm package to train my robot in pybullet. But I tried several times when the simulation reached around 30-40k steps, and the pybullet simulation's process was automatically terminated. I would like to ask whether I used the pybullet in the wrong way. Could someone help me to solve the problem? Thanks!
