Starting next week, May 27th, connections to Toolforge Redis [0] that remain idle for more than 10 minutes will be forcibly closed. [1]

This change is in order to prevent a situation where too many connections are active [2] and Redis stops accepting new connections, causing an outage [3] for several tools.

If your tool is using Toolforge Redis, we expect it to continue to work without issues, as most Redis clients automatically create a new connection to Redis in case an existing one is terminated.

If you have a tool that relies on long-lived Redis connections and would be negatively impacted by this change, please let us know.
