Thanks.
Have looked around a bit:
https://vborg.vbsupport.ru/showpost....87&postcount=6
--> at least 180
http://www.vbulletin.com/forum/showp...8&postcount=14
--> 28800 or 14400 or 7200 at least
http://www.vbulletin-germany.com/for...8&postcount=13
--> 1200
Quite a big range!
And could it be, that a too slow wait_timeout leads to "lost connection to mysql"?
So what is the best wait_timeout for a board with 200 to 300 users at the same time?
180?
