What do these database errors mean?

I got a bunch of this emailed to me today (and have gotten a few different ones here and there throughout the month) was wondering what they could mean?

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
/home/justfor1/public_html/includes/class_core.php on line 274

MySQL Error :
Error Number :

Script : http://www.worldformoms.com/admincp/index.php?do=home
Referrer : http://www.worldformoms.com/admincp/index.php?do=nav

Does this have something to do with my server not being able to handle my forums? do i need to upgrade to a bigger server? any advice is greatly appreciated!

It means someone has visited the forums, but vBulletin couldn't connect to the MySQL server for some reason. It usually means the MySQL daemon is down and was restarted (if it works now).

Thank you for clearing that up, I got freaked out when i got that error page and got emailed a bunch of times earlier today, it does work now :)

i thought i had to upgrade to a new server or something lol, thanks a bunch! ;)
