I have received the backup file you sent, so far I don't see anything out of the ordinary. But all of the messages are UDP I see, you mentioned that the issues were with receiving TCP right?
Thank you for the info on the LED. I do have a follow up question on that... Normally the LED does a slow pulsing of either white (=static IP) or red (=DHCP). I'm curious, when this lock up happens... Does the LED still pulse smoothly, or does it go in steps? The LED pulsing is directly controlled by the CPU, so when something is going wrong in the device the LED might tell us if the CPU is (too) busy or not.
Regarding the customer with the CueCore2 you mentioned, how and what are they sending over TCP? How many messages are there being send, what kind of time interval, is the network shared with other devices?
Thank you for the info.
Greetings,
