I am collecting information on Advanced SIM and sending to Azure cloud. I was sending messages on a time of 20 ms too simulate the cycle off the PLC. After more a less 4+ hours it crashes and i cannot acces node-red. I am unable to understand why. Any idea or how to discover the error? Best regards!

Are you then able to connect again? You can still check the log file if node-red was maybe the reason for it. It keeps old messages. If there is anything tagged with [error] node-red crashed. Best regards!

avaz Posts: 47 Rating: (0)	Yes sometimes it´s both i am waiting to see iwhen it crashes again if i can spot the error. YES! when i power on and off again everything is normal. The old files are deleted if i power off and on again, i saw the log files and only had new messages off the session :S [UPDATE] It got a new crash, the flow is simply sending a json file at a rate of 30 ms to AZURE.The last messages are normal..with no errors.

avaz Posts: 47 Rating: (0)	Indeed! Exactly i tried that..if i have for example a 60 second message send it doesn´t crash. I must deduze that has something to do with the speed off the flow or something

Can you check if you can access the second interface X2 after the crash? How does your network look like? How is the IOT connected? Can you test how fast you can go? Maybe the limit fulfills your requirements? And can you maybe share your flow? I'd like to understand what is happening. Best regards!
