Hello @CodeShepherd , after re-enabling the node-red application crashes again. It also seems that the whole app is accessible any more in that situation. We took another system report. It crashes at 11:15am approx. Regarding out use case: We are going to receive IO signale from the digital IO input (fieldbus) as well as from the PLC app. The fieldbus is used to receive 24v signals from different parts of the machine to verify if the machine is running or not. One input is used for automatic signal, another one for alarm, etc. In total we have 3 signals (Automatic state + Manual state + Alarm state). Further we are going to count IO signale from two light barriers (later it will be 4). The signals for the light barriers are true/false and will be counted within the PLC app to get real-time counters. All these signals are used within the node-red (subscriptions) to forwared this information to the kvd created parameters. The kvd parameters are offered from the OPC-UA server towards our ME-system. Meanwhile we also changed the counter detection from subscription to read-transaction. Therefore a trigger of 10 seconds is used. So normally it's a very small process regarding the input signals. We attached the current system report once more. Maybe you could take another look to this logs to verify if the problem which occurs is the same situation again. In case YES ... do you work on a solution? BR Markus
