IndexOutOfRangeException in WebSocket Server #269

Open invalidtask opened 1 year ago

invalidtask commented 1 year ago

Unfortunately this is all the info I can get on this error. It seems to happen after a few minutes of running/few thousand connections. What is causing this error? Is there a way I can capture this exception if it's a rogue connection causing the entire thing to crash?

.NET 6 (.NET 7 is not supported on this machine) NetCoreServer 6.0.7
