Device Limit on Open Balena Server

[luisgs7]

Hello everyone,

I currently have an open balena server with 355 registered devices, and I’m unable to add any more. Could you confirm if there is a limit on the number of devices an open balena server can handle, or if there might be another issue preventing me from registering additional sensors?

Do you have any more details, errors, etc.?

The Open Balena server is deployed on a VPS with 8GB of RAM and 4 CPUs on Linode.

I don't have any error logs, because no information about this appears on the server and I don't know where the logs are on the Balena OS.

I appreciate your attention, but I imagined that Balena would have a limit on the number of devices that could be on an Open Balena server.

AFAIK, there is are no device limits imposed at this (free) software level.

Open balena application versions export

OPENBALENA_API_VERSION_TAG=v0.209.2 export OPENBALENA_DB_VERSION_TAG=v5.1.2 export OPENBALENA_MDNS_PUBLISHER_VERSION_TAG=v1.9.2 export OPENBALENA_REGISTRY_VERSION_TAG=v2.25.3 export OPENBALENA_S3_VERSION_TAG=v2.13.10 export OPENBALENA_VPN_VERSION_TAG=v11.4.6

balena os version 6.3.23 and 2.113.18.

I already have more than 100 raps0 and rasp3 sensors on this open balena server, and I am unable to provision new sensors using this command: journalctl -u balena-supervisor rasp0 returns the following logs.
