### What happened/what you expected to happen?
We found sometimes workflow keep running for a long time. We investigated and found the root cause was the wait container of single pod in workflow stuck as the following:

We are very struggle about it. We don't know which caused wait container stuck. It's very hard to recure this bug.
### Version

Contributor guide
Research direction
No source file, test, reproducible workflow, controller log, or wait-container log is provided. Start by reproducing the stuck wait container on Argo Workflows 3.4.4 and collect the workflow pod state plus both controller and wait-container logs; done means identifying a repeatable cause and a verified fix.
