How to resolve 'isc_socket_bind: address not available' error in DNSProxy network extension?

hello

I am testing the use of network extension. When we use dnsproxy to proxy DNS requests, we will send you a message that the udp pcbcount of your system continues to increase. For example

for ((i=1; i<=99999; i++)); do

echo "Attempt $i:"

dig google.com

done

, when the dig command is used continuously, the dig command will show the following errors when pcbcount reaches a certain number.

isc_socket_bind: address not available

Can you help us determine what the problem might be? thank you
