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 -Jim Stapleton On 8/2/06, Richard Morse <[EMAIL PROTECTED]> wrote:

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?
