orbstack: Exited abnormally with signal 9

Describe the bug

OrbStack exited abnormally with signal 9. So I’ve checked logs and found this:

📦 scon | INFO[05-30 05:51:05] add forward                                   spec="{:: 18083 tcp}"
📦 scon | WARN[05-30 05:51:05] failed to apply listener changes              notAdded="[{0.0.0.0 7000 tcp} {:: 7000 tcp}]" notRemoved="[]"
📦 scon | ERRO[05-30 05:51:05] failed to update listeners                    container=docker error="listen tcp4 0.0.0.0:7000: bind: address already in use\nlisten tcp 0.0.0.0:7000: bind: address already in use"

...

📦 scon | INFO[05-30 05:51:57] remove forward                                spec="{0.0.0.0 7001 tcp}"
📦 scon | INFO[05-30 05:51:57] remove forward                                spec="{0.0.0.0 7000 tcp}"
📦 scon | INFO[05-30 05:51:57] remove forward                                spec="{:: 7001 tcp}"
📦 scon | INFO[05-30 05:51:57] remove forward                                spec="{:: 7000 tcp}"
📦 scon | WARN[05-30 05:51:57] failed to apply listener changes              notAdded="[]" notRemoved="[{0.0.0.0 7000 tcp} {:: 7000 tcp}]"
📦 scon | ERRO[05-30 05:51:57] failed to update listeners                    container=docker error="forward does not exist\nforward does not exist"

So the port number 7000 conflicts to other service that OrbStack exited with signal 9.

With this command, Can see the port number 7000 is already use in Control Center:

$ sudo lsof -PiTCP -sTCP:LISTEN 

OrbStack  2986 *****   72u  IPv6 0x*****     0t0  TCP *:4101 (LISTEN)
ControlCe 3368 *****    5u  IPv4 0x*****      0t0  TCP *:7000 (LISTEN)
ControlCe 3368 *****    6u  IPv6 0x*****      0t0  TCP *:7000 (LISTEN)
ControlCe 3368 *****    7u  IPv4 0x*****      0t0  TCP *:5000 (LISTEN)
ControlCe 3368 *****    8u  IPv6 0x*****      0t0  TCP *:5000 (LISTEN)

The port number 7000 and 5000 in MacOS is for AirPlay receiver. I think OrbStack should use another port instead of 5000 or 7000 but not sure.

To Reproduce

Steps to reproduce the behavior:

1. Turn on OrbStack
2. Turn On AirPlay receiver in System Settings
3. Use docker container like mysql in local
4. See error on OrbStack

Expected behavior

OrbStack exited abnormally with signal 9
