Engineering Logs for Troubleshooting & Debugging
Problem – Stop Sequence Trigger Failure in Development Sandbox Engineers using ChromaDB in a Docker‑based development sandbox report that the stop_sequences parameter supplied to query or generation calls is ignored. The symptom manifests as: Unbounded text generation that eventually exhausts container memory (OOM). Log entries such as: ERROR: StopSequenceError – Expected stop token not found … Read more
Problem: OOM Errors During High‑Throughput Vector Insertion Benchmarking When benchmarking ChromaDB on a single‑node VM (16 GB RAM, 8 vCPU) with 10 M+ 768‑dimensional embeddings, the Python process is terminated by the kernel after a few gigabytes of RSS growth. Typical failure messages observed include: MemoryError: Unable to allocate 1.2 GiB sqlite3.OperationalError: database or disk is full OSError: … Read more
Problem: ChromaDB Token Refresh Failure During Live Data Ingestion In a production streaming pipeline that continuously upserts embedded documents into a hosted ChromaDB instance, the following symptoms were observed after roughly one hour of operation: WebSocket connections dropped with connection closed with code 4001 (authentication_failed). HTTP 401 Unauthorized responses on /upsert and /add endpoints, e.g.: … Read more
Problem – Intermittent Batch Ingestion Failures in ChromaDB When a dedicated ingestion service streams large Kafka batches to the ChromaDB /api/v1/ingest endpoint, the operation fails with two distinct symptoms: ERROR – client: Connection reset by peer (errno 104) while sending batch upsert request. 504 Gateway Timeout – upstream request timed out (nginx ingress) while processing … Read more
Problem – Stop Sequence Ignored During Disaster Recovery During a disaster‑recovery (DR) operation on a multi‑node ChromaDB cluster, the configured stop_sequence was not honoured. The restoration process continued past the intended termination point, resulting in: Partial overwriting of existing embedding files. Duplicate document IDs across shards. Truncated vectors – up to 12 % of dimensions lost … Read more
Problem – ChromaDB Container Crash Loop on‑Premises OOM Error Deployments of ChromaDB on shared on‑premises servers often encounter a crash loop where the Docker container is repeatedly killed and restarted. Typical symptoms include: Docker daemon reports OOMKilled for the container. Health‑check failures such as HTTP 500 Internal Server Error from the /healthz endpoint. Docker logs … Read more
