I've recently been getting an issue where docker commands start failing because the connection through the forwarded socket is getting closed. It appears that the ssh process dies for some reason. While the socket is working lsof shows the ssh process has it open. But when the socket becomes unresponsive, lsof no longer shows this and the process id no longer exists.

from ~/.colima/_lima/colima/ha.stderr.log :
```
{"error":"unexpected EOF","level":"warning","msg":"connection to the guest agent was closed unexpectedlyunexpected EOF","time":"2023-11-30T23:21:26-05:00"}
```

Maybe in this scenario the port forwards could at least be re initialized. But it'd be great if we could avoid the ssh process dying altogether.
