As shown in the figure, after we upgraded version 9.2.0, wss soared after we deployed to the container environment. Can you help us find out why this problem is caused

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

What APIs do you use in your app?
The main change in v9.2.0 was deprecating sendAll(), sendAllAsync(), sendMulticast(), and sendMulticastAsync() APIs and adding sendEach(), sendEachAsync(), sendEachForMulticast(), and sendEachForMulticastAsync() APIs instead.

Do you experience the same issue in v9.3.0?
