Hi, since enabling mysql transaction logging totara is returning " Can not write database session - please verify max_allowed_packet is at least 4M!, referer: http://svytotara.com/user/editadvanced.php?id=12032&course=1", this appears in the the apache error log. I've increased max_allowed_packet in my.cnf to its maximum ( 1GB ) and still getting the error. If I disable transaction logging then totara works fine. Although its actually totara throwing the error and not mysql in lib/sessionlib.php. I can't determine what sessionlib.php is trying to check before throwing this error and howto resolve my problem. Thanks in advance for any replies.
