I'm just another epoll user, definitely not an expert.  Hopefully
somebody else can figure this out, because I'm unable to reproduce the
problem with your code and I haven't spotted any bugs from reading
through the kernel.

Curious, I also have a multi-threaded HTTP server which is a little
similar (multi-threaded, 2 epoll descriptors (only one epoll is heavily
used).  I run it on 2/4-core systems and haven't hit issues with epoll.

If you want to test, it should be easy to build from tarball:

  http://bogomips.org/cmogstored/files/cmogstored-1.0.0.tar.gz
  configure && make
  ./cmogstored --httplisten=8080 --docroot=/path/to/whatever
