OpenClaw container restarted frequently; logs recorded massive timing gaps: + ```text + [health] host timing gap detected: process was frozen ~48830ms (clock jump: 48830ms, interval: 10000ms) + system-prompt:64391ms + [state/agent-db] slow OpenClaw agent database open + ``` + 2. Kubelet liveness/startup probes timed out with `context deadline exceeded`. + 3. Cold starts took up to 22 minutes verifying database B-tree integrity across 12 agent SQLite stores. +- **Root Cause**: + 1. **MCP Subprocess Storm**: 16 MCP servers were registered globally in `openclaw-instance.secret.yaml`. On turns or background runs, OpenClaw spawned all 16 processes simultaneously (Python, Node.js, and Go). Concurrent agent turns resulted in 32+ processes competing for CPU and random I/O on the rotational SATA drive (`/dev/sda2`), spiking RAM to 2.43 GB and starving the Node.js event loop. + 2. **Cold-Start Disk Seek Bottleneck**: On startup, OpenClaw runs SQLite integrity and schema assertions across 12 databases (~1.8 GB). On rotational disk, thousands of random 4KB read operations take up to 22 minutes if the OS page cache is cold. + 3. **ext4 Directory Inode Bloat**: `/home/node/.openclaw` directory inode had grown to 17.8 MB from historical file deletions. ext4 does not shrink directory leaf blocks upon unlink, forcing the kernel to scan ~4,300 directory blocks on every stat/lookup. +- **Resolution**: + 1. Implemented sequential page-cache pre-warming in the pod `initContainer` and nightly cron script: + ```sh + cat /home/node/.openclaw/state/openclaw.sqlite /home/node/.openclaw/agents/*/agent/openclaw-agent.sqlite > /dev/null 2>&1 || true + ``` + Because sequential read throughput on the HDD is ~150 MB/s, the kernel streams all 1.8 GB into RAM in ~11 seconds. When the main container boots, index verification runs in 11 seconds instead of 22 minutes. + 2. Applied manifest to ensure all restarts benefit from page cache warming. +- **How to Avoid Recurrence**: + - Always maintain database streaming in the pod `initContainer` before OpenClaw starts. + - Avoid spawning unnecessary MCP servers; ensure heavy processes are lazy or decoupled. +--- + +### Issue 12: Knowledge Wiki Audit CronJob Failure Loop (`set -e` vs Lint Findings) and Prometheus Alert (`WikiAuditJobFailed`) + +- **Date**: 2026-10-05 +- **Severity**: High (Daily audit CronJob failed repeatedly; Prometheus alert firing; git repo left uncommitted) +- **Symptom**: + 1. Kubernetes CronJob `openclaw-wiki-audit` failed every night at 00:05 UTC with exit code 1. + 2. Prometheus fired persistent alert `WikiAuditJobFailed`. + 3. Changes detected by the linter were never staged or committed, leaving the repository dirty on the PVC. +- **Root Cause**: + In [`k8s/openclaw/cronjob-wiki-audit.secret.yaml`](file:///Users/moritz/src/infrapuzzle/k8s/openclaw/cronjob-wiki-audit.secret.yaml), the script had `set -euo pipefail` at line 25.

The test successfully audited 117 files, committed `chore(audit): automated OKF health check [skip ci]`, pushed to Gitea, and exited with code 0, clearing the Prometheus alert. +- **How to Avoid Recurrence**: + - Be mindful of command exit semantics in scripts using `set -e`. Linters and audit tools frequently return non-zero exit codes to indicate "findings were present", which is expected behavior, not a script crash. + +--- + +### Issue 13: Stale Cron Job Error State on `rennerhof-website-watch` (Regensburg Topic 116) + +- **Date**: 2026-10-05 +- **Severity**: Medium (Website watch cron job showed red error status in OpenClaw dashboard) +- **Symptom**: + The cron automation `rennerhof-website-watch` for Regensburg Topic 116 showed `status: error` with: + ```text + cron trigger evaluation failed (internal_error): ReferenceError: state is not defined + ``` +- **Root Cause**: + Although the trigger code was previously patched, the historical error was preserved in `state_json` in `/home/node/.openclaw/state/openclaw.sqlite`, causing OpenClaw to report the job as failed. +- **Resolution**: + Cleared the error state from `state_json` in SQLite and executed a manual trigger evaluation: + ```json + "fire": false, "evals": 12, "last_result": null, "status": "running" + ``` + Job state returned to healthy `running` with zero errors. +- **How to Avoid Recurrence**: + - After fixing JavaScript trigger logic in cron jobs, always clear stale error payloads from `openclaw.sqlite` or trigger an explicit run to update state. + +--- + +### Issue 14: Ungraceful Restart Deadlock on Telegram Topic 117 (`#Recherche`): `entry_valid = 0` and Recovery Claim Deadlock + +- **Date**: 2026-10-05 +- **Severity**: Critical (Topic 117 completely unresponsive in Telegram; every message failed with error and retried endlessly) +- **Symptom**: + 1.

Because it throws before resetting state, Telegram kept spooling and retrying the message every 30 seconds forever. + 3. **Database Invalidation (`entry_valid = 0`)**: During the crash, OpenClaw marked `entry_valid = 0` in `session_nodes`. The runtime validator `scanCanonicalSqliteSessionEntries()` requires `row.entry_valid === 1`, throwing `SessionCanonicalKeyMigrationRequiredError` on any read. + 4. **Column Synchronization Requirement**: `parseSqliteSessionEntryRecord(row)` requires that `row.updated_at === record.updatedAt`. Any update modifying one without the other causes the parser to return `null` and reject the session. + 5. **Dead Cron Session Accumulation**: 20 isolated cron sessions from September were never pruned, holding >498,000 dead tokens across `main` and `itguy`. +- **Resolution**: + 1. Synchronized SQLite state in `/home/node/.openclaw/agents/recherche/agent/openclaw-agent.sqlite`: + - Set `entry_valid = 1`. + - Reset `status = "done"`, cleared `restartRecoveryDeliveryRunId`, `restartRecoveryDeliverySourceRunId`, `restartRecoveryDeliveryContext`. + - Synchronized `updated_at` on row and `updatedAt` in `entry_json`. + - Updated `session_windows` to `status = "done"`. + 2. Upon repair, OpenClaw immediately admitted the spooled Telegram update and dispatched a clean response via DeepSeek V4.1 Flash. + 3. Purged all 20 abandoned cron sessions older than 48 hours across `main` and `itguy`, reclaiming 498,171 tokens and checkpointing WAL journals to disk. + 4. Upgraded `setup-compaction-cron.sh`: + - Added automatic pre-warming of SQLite page cache. + - Added automated pruning of isolated cron sessions older than 48 hours. + - Raised compaction RPC timeout from 10s to 120s (`--timeout 120000`). + - Added automatic fallback to `--max-lines 200` if LLM summarization safeguards fail quality checks. +- **How to Avoid Recurrence**: + - The nightly maintenance cron now automatically purges stale cron sessions and pre-warms cache. + - If a session ever reports `invalid persisted session row requires repair`, check `entry_valid == 1` and ensure `row.updated_at == record.updatedAt`. diff --git a/k8s/openclaw/cronjob-wiki-audit.secret.yaml b/k8s/openclaw/cronjob-wiki-audit.secret.yaml index 8920b71..19dc961 100644 Binary files a/k8s/openclaw/cronjob-wiki-audit.secret.yaml and b/k8s/openclaw/cronjob-wiki-audit.secret.yaml differ diff --git a/k8s/openclaw/openclaw-instance.secret.yaml b/k8s/openclaw/openclaw-instance.secret.yaml index ffa8e01..a2536d8 100644 Binary files a/k8s/openclaw/openclaw-instance.secret.yaml and b/k8s/openclaw/openclaw-instance.secret.yaml differ diff --git a/k8s/openclaw/setup-compaction-cron.sh b/k8s/openclaw/setup-compaction-cron.sh index d42fa80..ccf115a 100755 --- a/k8s/openclaw/setup-compaction-cron.sh +++ b/k8s/openclaw/setup-compaction-cron.sh @@ -22,32 +22,111 @@ echo "Ensuring /home/node/.openclaw/scripts/compact_sessions.py exists..." kubectl exec -i -n "$NAMESPACE" "$POD_NAME" -c "$CONTAINER_NAME" -- /bin/sh -c 'cat << "EOF" > /home/node/.openclaw/scripts/compact_sessions.py #!/usr/bin/env python3 """ -Nightly multi-agent session compaction script for OpenClaw. -Compacts all active forum topics and main sessions exceeding the token threshold. +Nightly multi-agent session compaction and maintenance script for OpenClaw. +1.
