I updated shmax in the kernel, which hasn't helped. I enabled mysql logging and don't see anything *too* obvious.
In the text below, group_id of 4001 is a valid group, but the group_leaders table never has any rows in it. I can't see any DELETES on that table besides when the server first starts up.
Not sure why it does the first update before the insert, though.
Code:
147 Query UPDATE group_leaders SET leadername = 'TestCharacter' WHERE gid = 4001
147 Query INSERT INTO group_leaders(gid, leadername, marknpc, leadershipaa, maintank, assist, puller, mentoree, mentor_percent) VALUES(4001, 'TestCharacter', '', '', '', '', '', '', '0')
147 Query UPDATE group_leaders SET leadershipaa = '\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0' WHERE gid = 4001 LIMIT 1
