[bug] I encountered a problem in the 17th iteration when runing the example

[shuhaom]

I followed the suggested steps to submit the example, but ran into such a problem on the 17th iteration, which did not occur in the previous 16 iterations. Can you tell me the possible cause and solution?

• 16th iteration out of 50 completed. [######### ]
