How to fix: Dagster webserver and daemon memory usage grows fast until OOM. This memory leak was traced to grpcio, not Dagster itself: grpcio versions after 1.57.0 leak in Dagster's webserver/daemon setup. Short-term fix: pin grpcio==1.57.0 (1.59.5 was also reported stable) in your Dagster deployment image.
The install failure on Python 3.11 comes from the old pinned grpcio==1.48.1, which does not work on 3.11. Upgrade to stability-sdk 0.6.1 or later, which added Python 3.11 support via PR #209. If you must stay on an old version, you can work around it with a requirements file pinning newer grpcio and grpcio-tools, but …
Problem outcome: unknown
Installing stability-sdk 0.3.1 on Python 3.11 Windows failed because the pinned grpcio==1.48.1 and grpcio-tools==1.48.1 could not build or resolve on 3.11. Maintainer johnsabath released 0.6.1 with Python 3.11 support and asked the reporter to try it. A user confirmed the issue was resolved by PR #209, which updated t…

Short-term fix: pin grpcio==1.57.0 (1.59.5 was also reported stable) in your Dagster deployment image. Durable fix: upgrade to grpcio>=1.68, which one user ran for a month with stable m…
Problem outcome: unknown
Dagster's webserver and daemon steadily grew in memory until containers were OOM-killed, even on small deployments. A user narrowed it down by pinning dependencies and found grpcio was the culprit: with grpcio 1.57.1 or newer installed, memory climbed fast; pinned to 1.57.0, the leak disappeared. A Dagster maintainer …
