Hello, first of all, I would like to thank you very much for the great work here and the development of neolink.
Everything works fine, but after every 30 minutes of running Neolink, I get the following warning:

WARN neolink::common::camthread] camera: Connection Lost: BcUDP reciver dropped: NoneRecieved
INFO neolink::common::camthread] camera: Attempt reconnect in 50ms

In this context, neolink increases CPU usage to 99% and the CPU becomes hot. The only solution is to restart neolink.

Here is the log:

after exactly 30 minutes again i get the warning and info again, cpu usage rising to 99% and the camera stream is freezed with timestamp of the warning

at the same time the mqtt broker log is:

2025-12-29 11:04:32: Client Neolink9fbf3568-6e1a-461b-8fd4-48803fc3e323 has exceeded timeout, disconnecting.

Now i can only restart neolink and it starts all over again.

It would be great if you could help. Many, many thanks.
