tool_stats: memory unavailable: {e}

Error message

tool_stats: memory unavailable: {e}

What it means

tool_stats queries the in-process memory engine for recorded tool usage; this fires when acquiring the active-memory guard fails — the memory subsystem/module is not available in this build or runtime — so stats cannot be served. It is an infrastructure unavailability, not a bad query.

Solutions

1. Verify the memory module/engine is enabled and initialized in this build
2. Retry once startup has completed if the memory subsystem was still booting
