Symfony2: intermittent high response time / slow completion SessionHandlerProxy :: read ()

Question

I see very strange behavior emanating from the Symfony2 Session Manager component. In particular, the SessionHandlerProxy :: read () function in my production environment is sometimes very slow.

Symfony\Component\HttpFoundation\Session\Storage\Proxy\SessionHandlerProxy::read

I use Apache2 on Amazon EC2 running Ubuntu with the default Symfony2 session repository (not Redis, or something similar), although I'm wondering if I should be. I have NewRelic installed to track my transactions that report the following:

Slow responses are intermittent, and I did not notice any noticeable correlation between requests / min and slow session read time. I'm at a standstill, any ideas what I can try?
