Sometimes on my VPS I get the error
Warning: mysql_pconnect(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) in /var/www/mysql.php on line 8
It can be solved by restarting MySQL several times, restating the sever or sometimes using mysqld command.
Using the mysqld command I get the following:

My get only 50 visitors a day and uses more than 3000 queries per hour. My VPS is only 1 core with 256MB ram and runs on Ubuntu 64bit.
MySQL downtimes directly affect my website and I can't find a answer anywhere.
Thanks in Advance :)
