Sorry, I may have misunderstood.  The three stack traces I attached are not 
related to btree.  I recall that I saw one stack trace containing 
bt_insert(), but I'm not sure.

When the hang occurred, INSERT/UPDATE/COMMIT statements stopped for at least 
one hour, while SELECT statements ran smoothly.
