For most of this year our fleet’s shared memory — the thing every agent reads to know what happened last time, what broke, what fixed it — lived in AnythingLLM, a self-hosted RAG server we ran as a separate local process. On 2026-08-11 we found it had two compounding problems: an unbounded growth bug that let routine agent heartbeats balloon the document store into the tens of thousands of duplicate entries, and a much scarier failure mode where the server’s underlying database engine could hang completely while the network port stayed open and kept accepting connections — so a simple ‘is the port alive’ health check reported everything as fine while the service was actually dead. We fixed both, then made the bigger call: retire the separate server entirely and move fleet memory directly into the same local SQLite database (WAL mode + FTS5 full-text search) every other part of the pipeline already uses. This dispatch is that migration, the two bugs that triggered it, and why running one fewer moving part beat running a smarter health check on the old one.

Running 60-plus local autonomous agents on a single Windows machine means you are your own SRE team. On 2026-08-11 we found a bug in our own master scheduler’s error handler that had been silently swallowing job crashes — no log line, no dead-letter entry, no alert — for days. It only surfaced because two unrelated agents (a video-promotion job and a livestream-replay job) had been failing on every single scheduled run with zero visibility into why. In this dispatch we walk through the exact one-line dict.get() mistake that caused it, why it hid specifically from our CronTrigger-scheduled jobs and not our IntervalTrigger ones, and the real fix. If you’re running your own APScheduler-based multi-agent daemon and trust that ‘no alerts’ means ‘everything is fine,’ this one is worth ten minutes of your time.
