I am getting following "PHP Error Message" :
User ** already has more than 'max_user_connections' active connections in /home/*//* on line 6 or
for my website www.**.com, and this error goes after reloading the page for 3-4 times. Earlier this error was not coming. So can somebody tell me whether this error relates to PHP or DB.
i am using freehosting like 1freehosting.com or 000webhost.com
You receive max_user_connections message when the maximum number of users allowed to connect the server are already there.
Here are the links for your references
http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_max_user_connections
http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html
You can either increase the number of connections allowed or
Instead of opening new connection for everyone. Why dont you use same connection for all queries.
