Been reading through about 300 log messages in one folder - no problems
since switching to file-based sessions on a test server.  I was asking
simply to confirm that message indexes are stored as a session variable.  If
they are not, them I'm going on a wild-goose chase.  Reading through those
messages without error doesn't prove that MySQL-based sessions are the cause
of the problem, because it could be some other lurking influence causes the
index problem.  But there's enough circumstantial evidence to leave me to
believe we have a MySQL race condition, if using that type of session to
store session info.

My comment earlier on this ticket about reloading the left frame, which
caused the "Requested message not found" error to go away in my INBOX I
think contributes to my believe that this boils down to a MySQL-based
session race issue.

A discussion that I think talks about this issue, in general, is at:

http://www.issociate.de/board/post/184369/warning_&_question_about_mysql_ses
sions_&_concurrency.html

Since sites that use multiple web servers for load-balancing and failover
would likely used a shared session mechanism, such as database-based, I
think this is important to fix (of course, assuming it is a race condition -
I could be quite wrong about that).
