Gary Tully commented on AMQ-4094:
---------------------------------
a workaround is to avoid page overflow by configuring a large index page size
for kahadb. The size needs to be > any single stored value. In the case of
offline durables with selectors the sequence set of pending messages needs to
fit in one page.
> offline durable subs with selectors can lead to page leaks in the index and
> bloat of db.data in kahadb
