| Dear vb Team, Please help me in this issue: how high we set the max_user_connections (currently set to 200) in MySQL, gradually MySQL overloads with queries such as this: --- SELECT post.dateline, post.pagetext AS message, post.allowsmilie, post.postid, thread.threadid, thread.title, thread.prefixid, post.attach, forum.forumid, user.* ,avatar.avatarpath, NOT ISNULL(customavatar.userid) AS hascustomavatar, customavatar.dateline AS avatardateline,customavatar.width AS avwidth,customavatar.height AS avheight FROM post AS post JOIN thread AS thread ON (thread.threadid = post.threadid) JOIN forum AS forum ON(forum.forumid = thread.forumid) LEFT JOIN user AS user ON (post.userid = user.userid) LEFT JOIN avatar AS avatar ON(avatar.avatarid = user.avatarid) LEFT JOIN customavatar AS customavatar ON(customavatar.userid = user.userid) WHERE 1=1 AND thread.forumid IN(25,26,107,28,111,135,115,114,122,123,133,125,13 0,126,226,127,128,129,112,154,131,29,132,162,106,1 10,147,27,117,146,145,3,4,5,59,38,39,40,41,42,43,4 4,182,45,46,47,66,6,63,227,149,150,151,152,202,203 ,204,205,206,120,207,208,209,229,230,231,232,233,1 6,17,103,102,215,211,218,18,214,19,21,23,160,161,1 83,74,24,139,141,140,224,225,22,1,90,65,7,8,64,220 ,163,2,134,144,119,53,60,61,159,185,124,186,187,62 ,136,137,138,166,9,109,158,157,164,118,55,12,148,1 1,10,210,81,82,116,83,84,189,190,191,192,193,194,1 95,196,197,198,199,200,201,212,30,31,32,51,52,167, 168,169,170,171,172,173,174,176,177,179,181,180,75 ,48,100,50,49,105,15,88,93,94,101,95,96,97,98,216, 222,228,99,153,219,155,221,217,85,223) AND thread.visible = 1 AND post.visible = 1 AND thread.open 10 AND post.dateline > 1264352298 ORDER BY post.dateline DESC LIMIT 0,8 --- what on the site executes that query and if they have any advise with regard to preventing it from overloading MySQL.
