Answer 1

I covered this in a blog post a while back. Basically, this is happening because eAccelerator is stripping out docblock annotations as an "optimisation". The problem is that Doctrine is relying on these annotations to map your entities.

There are two possible solutions:

1. Don't use eAccelerator. There are much better opcache tools available e.g. APC or PHP's built-in OPcache (PHP 5.5+).
2. Disable this behaviour in eAccelerator. You can do this by compiling eAccelerator with the --with-eaccelerator-doc-comment-inclusion flag, or use a newer version of eAccelerator which disables this behaviour by default.
