Google Cloud SQL和Wordpress“连接太多”

I´m having Problems with my Wordpress Setup and Google Cloud SQL.

I don´t have any Users than me on my Website yet, but even when i visit my site with a couple of tabs the CPU load and Memory Increases fast to the Maximum. Also i sometimes get a MySQL Message from WP that there are too many connections.

I guess 250 is Max. and i often hit it.

I cannot see any D.O.S. attacks so it has to do with my own Config i guess.

I´m Using:

• Wordpress on Google Compute Engine
• Cloudflare with Flexible SSL
• W3 Total Cache
• WPML (database cash with memcache, Object Cache, etc.)

Does someone have any ideas what could cause that failure?

I also have Problems with pageload time. Could redirection Problems causing this Problem?

How to debug a Google Cloud-SQL as i don´t have no access to the Engine it self?
