Yes, I clicked on the ReadNode while it was running, which interrupted the update.

Secondly, I tested 1000+ quantities of continuous output in subscription mode. Will computer hibernation cause it to interrupt updates? When I went to do other things for about an hour, I came back and found that the subscription callback method would no longer be executed, that is, it would stop updating.

Yes, it is a node subscription model. Whether the number of nodes is 100+ or 1000+, in a testing environment, my setup consists of CX-Programmer + kepserverEX + Unity 2022. Initially, Unity runs very stable, continually updating the debug.log data. However, at some point, for reasons unknown, it stops updating, and all data ceases to refresh. Data only updates once when the 'Read Node' is specifically clicked, without continuing to track further changes. Yet, my CX-Programmer and kepserverEX statuses appear normal~
