I think you should not autostart session. In case framework.session.auto...

After some research i found that turning off session autostart is not a silver bullet. But this is correct with this bundle i found: https://github.com/gillest/HackSessionBundle

I dont like Hack prefix but it does the job.

Even while I run php app/console cache warmup, the session is created, here is an exception I throw while cache is warm:
