Hi! All of these queries worked just fine, without causing any
problems.
As this is more of a mysql issue, do you have any suggestions where
it would be best for me to query them?
Thanks,
Ricky

Not sure, seems more of a mysql question, but here's some guesses I
have for diagnostics.
could you run these queries?
SELECT COUNT(*) FROM users WHERE status < 3
SELECT COUNT(*) FROM sessiions WHERE sid =
"d9fe25949f79f2c767a0d237b4fdf841"
SELECT COUNT(*) FROM FROM users u INNER JOIN sessions s ON u.uid =
s.uid WHERE s.sid = "d9fe25949f79f2c767a0d237b4fdf841" AND u.status <
3

Hi! Since this time, I have, I think, found what query is causing
the problem:
SELECT u.*, s.* FROM users u INNER JOIN sessions s ON u.uid = s.uid
WHERE s.sid = "d9fe25949f79f2c767a0d237b4fdf841" AND u.status < 3
LIMIT 0, 1
How can I determine _why_ this is causing MySQL to hang/enter some
kind of infinite loop?
Thanks,
Ricky
