> This looks to be because of an infinite loop during fetch response send. This
> happens because we try to send bytes from a log which has been truncated
> during send. The total size to send is calculated at the beginning of the
> iteration and it does not take into account the change in log size during
> send. When send happens, it uses the size calculated at the start and loops
> continuously hoping to send more data.
