Oleg Kalnichevski commented on HTTPCORE-735:
--------------------------------------------
> the application can only be restarted
[~qxo] This is precisely the purpose of Error.
The cause of the problem is idiotic handling of Errors by your code. If you
decide to catch and ignore an Error, you also must reinitialize all application
components that could have been affected by it.
