After update to Cloudron 5.2.3, redis runs out of memory



  • Over night, my Cloudron was updated from 5.1.5 to 5.2.3 (automatically). Now I have hourly reports that redis for Nextcloud ran out of memory.

    The /redis-e8e62411-6b94-4669-8b43-b59fb95f4aa8 service ran out of memory

    The memory limit for Nextcloud is already set to 4096 MB and 50 % CPU.

    Edit: I see, there's a (new?) submenu on "System" for redis RAM for each app. Redis was set to 300 MB for each app. I increased redis for Nextclodu now to 1024 MB. The Nextcloud App is running now.

    @necrevistonnezr indeed, previous versions of Cloudron would allocate more memory for redis based on the app's memory limit. This limit was not settable by the user. In 5.2, we have made the redis limits visible and configurable by the user. Our 5.2 migration script should ideally could have been smarter and allocated more memory to redis.
