Horizon and open connections


We have horizon running based on the Ubuntu Folsom Cloud Archive packages.

What I notice is that after a while we have thousands of connections in the CLOSE_WAIT state to keystone and our nova api servers. 
The host also uses up all it's available memory (2GB)

After a restart of apache all the connections are cleaned up and the memory used drops down to about 200MB

Just wondering if this is supposed to happen or is there a bug. It seems to me that horizon isn't closing connections or something.

Anyone have a similar issue/solution?
