This is a server issue. See this: http://www.vbulletin.com/docs/html/t...mysql_goneaway and this: http://www.vbulletin.com/forum/showt...265#post310265

If you change the wait_timeout in my.cnf, don't forget you have to restart mysql in order for it to take effect.

i change that to 28800 as its shows

but when i root that "- mysqladmin -u root -p version it give me to enter the password and send me that error ?!



mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

I know I have a different username/password I have to use to access mysqladmin (I can't use root). That may be the case for you, but you will have to ask your host about that.
