Possibly related, but my failure appears to happen earlier, during reasoning/context recovery rather than inside Python/container execution.
Environment
- ChatGPT Plus
- Web, Microsoft Edge on Windows
- 29 September 2026
- GPT-5.6 Sol
Symptoms
- Existing long-running development chat showed
Analysis paused. - Later turns displayed
Analyzedrepeatedly on separate lines, with no substantive response. - Some attempts then showed only the pulsing activity circle and never progressed.
- I reproduced the same behaviour in a brand-new chat, so this does not appear to be caused solely by a long conversation.
- Both Instant and Medium thinking modes were affected.
- The fresh chat contained only a handover/seed prompt, one previous-build ZIP, and two small screenshots.
Important detail
I manually stopped one stalled turn. ChatGPT then reported from its execution trail:
“I did not get as far as modifying Build 100, running tests, or packaging a new build. I stalled in reasoning/context-recovery.”
So in this case the turn appears to be stalling before file modification or tool execution begins, rather than failing while Python/container code is already running.
Observed pattern
The system intermittently recovers and can complete small graphical/code changes successfully, then later falls back into the same stalled state.
This looks related to the execution/orchestration problems reported here, but possibly at an earlier stage in the pipeline. A fresh chat did not reliably clear it.
Happy to provide screenshots/timestamps if useful.
