Thanks for the logs. It looks like the compaction operation took too long, so the client's timeout was triggered.
Have you seen this more than once, or was this a one-time occurrence?

This issue keeps occurring: when there is very little context remaining, the context cannot be compressed, preventing the main task from continuing. It's very frustrating.

@etraut-openai This looks like the same compaction-timeout failure as #9211 (same error + same “timeout waiting for child process to exit”). Might be worth consolidating these so the reports/log threads are in one place.
This issue thread:

same error with
timeout waiting for child process to exitOr mention your thread ID 019c037a-73ff-7202-994c-701e51523059 in an existing issue.

@adogwangwang and @mumong, thanks for reporting. Are you on a corporate network/VPN/proxy that you know of? We don't set an explicit timeout ourselves, so trying to see what's terminating the connection.

@sayan-oai @etraut-openai This looks like a duplicate of #9211 — same exact error string (
Error running remote compact task: timeout waiting for child process to exit) and same Linux repro (auto-compact or using thecompactcommand). Suggest consolidating discussion there and closing one to reduce fragmentation (can carry over any extra details from this thread).etraut-openai commentedon Feb 9, 2026
Closing in favor of #9211.
