Why does it do this sometimes?

[Todd Goad]

Sometimes I click on a Topic and this appears: Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (11) in /home/httpd/html/bb.steelguitarforum.com/db/mysql4.php on line 48

Warning: mysql_error() expects parameter 1 to be resource, boolean given in /home/httpd/html/bb.steelguitarforum.com/db/mysql4.php on line 330

Warning: mysql_errno() expects parameter 1 to be resource, boolean given in /home/httpd/html/bb.steelguitarforum.com/db/mysql4.php on line 331
phpBB : Critical Error

Could not connect to the database.

Does anyone have any idea what causes this? I can hit the back button and the click on the topic again and most of the time it works fine. Using I.E> and Windows 7.

Thanks

Just a hiccup in the server, as it tries to contact our database where all topics and comments are stored. b0b probably needs to optimize the database to get rid of overhead.

Thanks Wiz!! I wasn't sure if I may a virus or something else going on with my computer.

Thanks again!
