I wonder how many active connection on each page of my Q2A installation?

 

I am having the following message many days a week:

Warning: mysql_connect() [function.mysql-connect]: Can't create a new thread (errno 11)

 

I googled for it and I found that it means I am consuming the max limit of connections per user at a time which mean much memory usage.

Is Q2A using many connections on each page? Or am I getting DoS attack?

Any solutions?

There should only be one connection per page load, but if you're getting many visitors that will be multiple connections per second/minute.
