Andre Bogus commented on LOG4J2-520:
------------------------------------
This Bug has been referenced from LOG4J2-392, which is basically the same with
async loggers instead of async appenders. With the current snapshot, the
problems boil down to the same behavior.
What happens is that the shutdown sequence leaves not enough time for async
{loggers, appenders} to write out the messages that still reside in the {ring
buffer, queue}. They are just shut down without so much as a warning.
The obvious solution is to allow for a grace period before shutting down async
{loggers, appenders} and to raise an error (at least a status error message)
when they fail to flush out all state to disk.
@Remko: Thank you for looking into this.
Regards,
Andre
