When I close it frequently, there will be an unrecoverable panic.

[Capybara-1]

I'm sorry that I used this framework in a strange way again.

When I frequently shut down gen.Tcp during the test

There will be an unrecoverable crash.

e.g.

My code is as follows.

My Sup Strategy Is

Strategy: gen.SupervisorStrategy{
Type: gen.SupervisorStrategyOneForOne,
Intensity: 10,
Period: 1,
Restart: gen.SupervisorStrategyRestartTransient,
},

Child Spec is

return gen.TCPOptions{
Host: args[0].(string),
Port: args[1].(uint16),
Handler: &handle{},
NumHandlers: 10,
MaxPacketSize: math.MaxUint16,
ExtraHandlers: true,
}, nil

The specific log is as follows
