What issue are you seeing?

I am frequently hitting a remote compaction failure in Codex on a Linux server environment.

Full error message:

Error running remote compact task: stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses/compact)

My setup uses a large context window (around 400k), with auto-compaction configured to trigger at around 240k. The problem occurs repeatedly even when the session still has more than 40% context remaining, so it does not seem to happen only when the conversation is close to the hard context limit.

This is happening in a remote/server Linux workflow rather than on a local desktop machine. The failure appears during the automatic compact step and interrupts normal usage. In my experience, this happens regularly in long-running sessions.

What steps can reproduce the bug?

Any session needs context compact have its possibility to reproduce the bug.

What is the expected behavior?
