Hi @volpima.
Thank you for your interest in ThingsBoard IoT Gateway.

Hi @volpima,

This issue relates to some modification of data sending, please try to use the latest version.

Hi @imbeacon thanks for your support.
Do you mean the 3.4.6 for IoT gateway?

Yes, unfortunately it sill be can unstable, we are working now with rate limits per each device created through the gateway, but it is more stable than 3.4.5

[volpima]

Hi @imbeacon any news regarding this issue? Unfortunately, this solution is really unstable; the problem reoccurs every few hours, and the MQTT communication between the IoT Gateway and Thingsboard Community Edition is interrupted, preventing the transmission of data from the Modbus source.
Do you have any suggestion?

I noticed this error before the disconnection. Is there a way to automatically restart the service if an error occurs?
