route_listen_stream blocked after about 1 hour on MacOS 15.0 Beta

[vczr]

hey guys, now i have a problem. I have a rust application to fix my route’s default role when the default role is deleted, like this :

It works well for the first hour. But after one hour, the listener can't receive events. At first, i thought the listener is break by some reason. So i put the code in a loop ,like this: But line 103 is never printed.

Can anyone give me some suggestion? Thanks!!
