Why does dbt docs serve timeout after a period of time?

Description

Hi, Everyone
Now I have encountered one question.
Because we apply dbt to our k8s and provide dbt document for user review through executing dbt docs serve.
And we found after a few hours, the docs server will show 504 gateway timeout.
After tracking, we found the below error message:

 BrokenPipeError: [Errno 32] Broken pipe Error

Does anyone have ideas how to solve it? I will be appreciated it.
