Sorry for my English. Recently I encountered a very serious problem. My server (built on Ubuntu with headless mode) sometimes stops responding and the CPU usage reaches 100%. I checked the log and found there were many repeated error: “HandleData Unknown connectionId:336”. And the client(mobile device) sometimes has a crash issue when join server, I guess it may be related to this.
I really want to know why it happened. My game is published. This issue occurred during the recent update, but I didn’t find out where my code might lead to an infinite loop.
By the way, my unity version is 5.6.3p4. And both server and client are using the unet.
