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?
Hi @luisgs7 , could you post more details about the server and where it is running. Also any logs from the API service would probably be useful. There isn’t anything outside of server resources that would limit this, so it might be due to the VPC instance you are running on.
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.
