index loading trouble

[Flying Dutchman]

Yesterday for a small time I was unable to load the index page. Dunno if it's solved or it'll come back, but here's the error I got:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/tmp/mysql.sock' (111) in /home/mith/public_html/forum/db/mysql4.php on line 48

Warning: mysql_error(): supplied argument is not a valid MySQL-Link resource in /home/mith/public_html/forum/db/mysql4.php on line 330

Warning: mysql_errno(): supplied argument is not a valid MySQL-Link resource in /home/mith/public_html/forum/db/mysql4.php on line 331
phpBB : Critical Error

Could not connect to the database

It happens occasionally, but root cause is unknown. I suspect it's something with the host.

P.S. Please don't flag things as BUGs unless you can prove that it's a bug (i.e. you can provide a patch file to fix it). In this forum, I'm using BUG indicates a problem with the forum itself. This is unlikely to be a problem with the forum, just a poorly handled exception.
