[Question] Several "Unable to poll" errors multiple times per day

Hey folks,

We've been using this ruby for quite a while, 1 year I would say and since then, we've been seeing a lot of "Unable to poll" errors. For example, last week, there were 700 of those for one of our service. This affects all our different using this sdk.

```
Unable to poll Workflow task queue

#
```
And this
```
Unable to poll activity task queue

#
```

Would someone have an idea of what might be causing those errors? Are they "normal" or expected from time to time within Temporal? We don't have a fancy configuration or anything we mostly use the default config and we use 20 as the thread pool size for both activity and workflow. I can share more relevant details if needed.

Note, this error doesn't cause any of our activities or workflows to fail, it just happens once every now and then and recovers.
