ELS61T with J2ME app suddenly restarts | Thales IoT Developer Community

I'm just pushing on on my journey to a stable application platform on ELS61T terminals.
Now the pressing issue is frequent sudden module restarts. In 24/7 operation, there can be intervals when modules restart every couple of minutes, then all is well for some hours. In general, at least 3-5 restarts happen daily (30+ devices).
Scanning the forum posts I found https://iot-developer.thalesgroup.com/threads/bgs5t-restart-after-few-i2c-readwrite-commands talking about I2C bus conditions (pull-ups) as a source of restarts. As we are using I2C comms in this project, this is a candidate for causing these events.
As I'm not very proficient in electronics, can someone explain in layman's terms about what are the requirements for a stable i2c communication with ELS61T. We have 2 Arduino Nano Every microcontroller connected to it.
Thanks in advance for any insight!
