1 month ago Hi @Crissbenavides,
Could you set logging level to DEBUG and after encountering the issue send logs to us (service log, tb_connection log and connector log files)? It will be helpful for investigation.
Describe the issue I have ThingsBoard Gateway installed on a Raspberry Pi 4 with 8GB of RAM, to which I have connected a serial device that measures the temperature through three thermocouples (I send the temperature of these three sensors). The problem arises when I use the Modbus connector: the data transmission works correctly for about 30 minutes or so, but then stops. I have checked the ThingsBoard Gateway logs and I can't find any error message to help me understand what is going on. When I run the command "systemctl restart thingsboard-gateway", the system starts working correctly again, but after about 30 minutes, the transmission stops again.
As a bonus, this problem also happened to me when I installed tb gateway in a virtual machine with ubuntu.
Last but not least, I am using the 30 day trial version of Thingsboard cloud.
