+title: New limits for Supervisor Add-ons
+---
+
+With Home Assistant OS 10, we update to the latest Docker release 23.0. With the
+new Docker version the maximum number of open file descriptors for add-ons
+changed to infinity (sort of).
+
+If you are an add-on developer and experience out-of-memory issues on Home
+Assistant OS 10, you can apply the old limit by using `ulimit -n 1048576` before
+starting your service.
+
+Background: During Home Assistant OS release candidate phase, the higher limit turned out to
+be problematic for several add-ons (Node-RED, Network UPS Tools, and the EMQX
+MQTT broker, see [Home Assistant OS issue #2438](https://github.com/home-assistant/operating-system/issues/2438)).
+In all cases, the problems manifested as an out-of-memory error,
+where it worked on the same hardware as the previous Home Assistant OS release. Also
+in all three cases, memory got allocated dynamically depending on the number of
+open file descriptors allowed (which can be determined via `prlimit64` syscall,
+which returns a limit of 1073741816).
+
+We considered returning to the old limit; however, according to the change
+in the Docker (moby) repository using infinity as a limit has less overhead.
+Therefore we decided to stick with the new default.
