PHP Warning: MySQL user already has more than 'max_user_connections' active connectio

[Zean]

Update: So, I took DrByte's advice and started by looking at my raw access logs. I found for this 1 minute time period all were from the same IP. There was over 350 hits from that IP during the 1 minute. I'm not sure what that means. However, a little googling, etc and I found webmasters have been complaining about that IP for years. The IP is 4.79.204.xx which I have partially masked for privacy reasons. Please check your raw access logs and let me know if you have a similar finding.

I too am on Blue Host and very recently upgraded to 1.5.4 and coincidentally threw over 50 identical PHP Warnings in less than 1 minute on July 2.

PHP Warning: mysqli_connect(): (42000/1203): User xxxx_yyyy already has more than 'max_user_connections' active connections in /zzzz/xxxx/public_html/shop/includes/classes/db/mysql/query_factory.php on line 62

So, Whitebear and Lat9, what have you found out?

PS. I do not have any reason to suspect it is a 1.5.4 issue.
