Environment

Windows10&11
Base Station 2.0
UDCAP gloves + Vive Tracker 3.0
Slime Tracker (BNO085) × 8

Issue encountered:
When the tracker briefly loses tracking, slime-server freezes. The duration of the freeze increases with the length of the tracking loss.

Possible cause (personal speculation):
The issue may be related to the UDCAP gloves. When the tracker loses tracking, the feeder displays a significantly abnormal number of disconnection messages, which might be too numerous for the server to handle.

I attempted to include two screenshots of the feeder to show the number of error messages after 10 seconds of tracking loss. Since I have not used this feature before, if the images are not displayed properly, I will try alternative methods to upload them.
