----------------------------------------------------------------
This error log happens approximately every 2 hours with the load 5-10 ssh
sessions per second. No prior problems for the questionable connection are
logged.
I would appreciate better logging for this case:
- Make a slightly different message for cases {{f.isWritten()}} and {{else}} so
future investigation would help
- Check if {{writeState.pendingWrite}} is already null and probably do not log
this case as error
was (Author: xvost):
Sure, will try do to it tomorrow. In any case better logging is welcomed here.
At least to tell two similar log places from each other, and to check if
`writeState.pendingFuture` as actually null
> Race condition is logged in ChannelAsyncOutputStream
