Bug

After context overflow auto-compaction succeeds and the prompt is retried, the session remains stuck in processing state indefinitely with queueDepth=0. This blocks ALL incoming messages across all channels until a gateway restart.

Environment

  • OpenClaw 2026.4.21 (f788c88)
  • Model: openai-codex/gpt-5.4
  • Compaction mode: safeguard
  • Context pruning: cache-ttl, 1h TTL

Reproduction

  1. Long-running session (~185-399 messages) hits context overflow
  2. Auto-compaction triggers and succeeds
  3. Log shows: auto-compaction succeeded for openai-codex/gpt-5.4; retrying prompt
  4. Session stays in processing state forever
  5. Diagnostics flag: stuck session: sessionId=main state=processing age=Xs queueDepth=0

Logs

20:07:56.630Z warn agent/embedded context overflow detected (attempt 1/3); attempting auto-compaction for openai-codex/gpt-5.4
20:12:50.808Z info agent/embedded auto-compaction succeeded for openai-codex/gpt-5.4; retrying prompt
20:15:20.872Z warn diagnostic stuck session: sessionId=main sessionKey=agent:…6191 state=processing age=149s queueDepth=0
(stuck for 5+ minutes, never recovered)

Impact

  • All channels stop receiving responses (single session blocks everything)
  • Only fixable by gateway restart
  • Happened twice in 30 minutes on same session

Expected

After compaction succeeds and prompt retries, the session should return to idle state after the retry completes (success or error).
