> I suspect there is a rare case where a {{SegmentBufferWriter}} is not flushed from the {{SegmentBufferWriterPool}}. This would happen after OnRC when a previous writer is [disposed|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-segment-tar/src/main/java/org/apache/jackrabbit/oak/segment/SegmentBufferWriterPool.java#L194] (vs. being re-used). AFAIU this currently those writers would never be flushed any more and thus lose their transient segment when the store is shut down. This will lead to an inconsistent store ({{SNFE}}).
