[Bug 1216817] Re: Using `fastcgi_cache` or `proxy_cache` with nginx-extras causes the push module to throw errors.

[Vorobyoff Andrey]

Hello!
I'm using Ubuntu Server 14.04.1 in VM

# cat /etc/issue
Ubuntu 14.04.1 LTS \n \l
# uname -a
Linux vm-newsru-fe-02 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

I'm using nginx
# dpkg -l | grep nginx
ii  nginx-common                     1.4.6-1ubuntu3.1              all          small, powerful, scalable web/proxy server - common files
ii  nginx-extras                     1.4.6-1ubuntu3.1              amd64        nginx web/proxy server (extended version)

I use nginx for proxying with cache.
Cache size set to 1024M but it is growing much more because nginx cache manager do not work:

# tail /var/log/nginx/error.log
