Gary ,Verwers commented on LOG4J2-3619:
---------------------------------------
I looks like the cursor sequence and the gated sequence are the same value.
At that point neither can move forward. But something in the consumer process
had to already be stuck for the producer to catch up. I have seen differences
of 2 to 30 minutes between the first log event and the last log event in the
ring buffer.
> Log4j stops logging when the log message contains a
> java.lang.StackOverflowError

> The RingBuffer Consumer stop printing logs when it comes to a log event with
> an exception connected with a StackOverFlowError attached. We have had
> this occur several dozen times.
> Both the cursor and the gate point at the same place in the event buffer and
> very quickly all the threads on the server are frozen waiting for the ring
> buffer to clear up space. But the consumer is just stuck waiting a not
> printing event. It has failed with a stack overflow from spring MVC mapping
> and it has failed with a stack overflow from Jackson JSON ObjectMapper with
> object level recursion triggering a stack overflow.
