j1wonpark opened a new pull request, #58308: URL: https://github.com/apache/spark/pull/58308
### What changes were proposed in this pull request? Backport of #58205 to branch-4.2: run the request loop of `TransformWithStateInPySparkStateServer.run()` inside `Utils.tryWithResource` so the accepted socket is always closed. This branch does not have SPARK-58977, so unlike master the `accept()` call is unchanged. ### Why are the changes needed? The accepted socket is never closed, leaking one file descriptor per task until the executor exhausts the ephemeral port range (`java.net.BindException`). See #58205 for details. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The two tests added in #58205 are included; `TransformWithStateInPySparkStateServerSuite` passes locally on this branch. ### Was this patch authored or co-authored using generative AI tooling? Yes.
