Cmdstanpy error signal 3221225349

Dear stan experts,
I am trying to fit a model with cmdstanpy and suddenly a error came out that chain 1 is terminated. Here is the error warning. What’s the meaning of this warning? Thanks.

cmdstanpy - ERROR - Chain [1] error: terminated by signal 3221225349

Hi, @zaizibai. Sorry nobody answered your original post. We usually need more context to answer questions. Can you say what Stan program and data you were running and exactly which command led to this answer? Then @mitzimorris should be able to sort out what went wrong.
