Do we understand how this could happen and are we able to reproduce the error?

I don't think we understand how this could happen, @igorbernstein2 tried to add the stacktrace so we might be able to figure it out next time it happens. This is not reproducible either by customers, we might be able to reproduce it by digging really deep into the codebase.
In the internal bug I see some ideas. Can we try to reproduce them?
The count of outstanding RPCs in ChannelPool could go negative in some cases, and an exception would be throw. In such case, there is no way a customer could recover from such error. See internal issue for details.
We need to prevent the count of outstanding RPCs to go negative and also figure out why this happened.
