UDP Proxy crashes

Hi guys, I am trying to host my own teamspeak server on a LXD container. I have forwarded the UDP Port 9987 via a proxy device to the container and everything works about 20 minutes.
After the 20 minutes it seems that the proxy stops working anymore. If i execute
lsof -i -n | grep 9987
no listener is reported.

I’ve looked into the proxy log file and there is following error:

panic: runtime error: racy use of timers

goroutine 36 [running]:

Can somebody help me?
