With ziti 1.5.4 I have about 34 error every 12h on 6 routers:

```auto
      2 "payload buffer closed"
      3 "failed to dial fabric"
      3 "failure while handling route update"
      4 "terminator was replaced after being put into deleting state?!"
      6 "unable to forward payload"
     16 "failure to buffer payload"

```

With ziti 1.6.7 I have an error every 1 minute.

I should also add the following:

```auto
{
  "file": "github.com/openziti/ziti/router/xgress_edge/hosted.go:267",
  "func": "github.com/openziti/ziti/router/xgress_edge.(*hostedServiceRegistry).RemoveTerminatorsRateLimited.func1",
  "level": "error",
  "msg": "terminator was replaced after being put into deleting state?!",
  "terminatorId": "XD6xzbPRpygapI4l3TGSA",
  "time": "2025-08-19T14:17:55.472Z"
}

```

I am back to 1.5.4
