Andrei Dulceanu commented on OAK-6915:
--------------------------------------
Interesting findings, [~frm]! You may want to take a look at how
{{SegmentCache}} looks like on my branch [0], because it needed some code which
currently lives in {{FileStore}} for handling {{SNFE}}s thrown while standby
tries to load segments.
