codex - 💡(How to fix) Fix Multiple sub-agents + typing randomly breaks TUI [2 comments, 2 participants]

TL;DR

The issue is likely related to a threading synchronization problem when running multiple sub-agents in parallel, and a potential fix could involve modifying the Codex CLI to handle threading more efficiently.

Guidance

• The problem seems to occur when running 4+ sub-agents in parallel, so trying to reproduce the issue with a smaller number of sub-agents may help isolate the problem.
• Reviewing the uploaded thread (019df509-ba14-7320-97b7-a5e14eb4f5a2) may provide more insight into the threading synchronization issue.
• Temporarily reducing the number of sub-agents run in parallel may serve as a workaround to prevent the TUI from hanging.
• Investigating the Codex CLI's threading implementation and potential deadlocks or race conditions could help identify the root cause of the issue.

Notes

The issue seems to be related to the specific version of Codex CLI (v0.128.0) and the Pro subscription, but without more information about the Codex CLI's internal workings, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: reducing the number of sub-agents run in parallel, as this may help prevent the TUI from hanging while the underlying issue is investigated and addressed.
