Could anybody explain me why I have this behavior and if it is attributable to a misconfiguration of php?

This doesn't look like a PHP misconfiguration. It looks more like an application-level issue. Do a grep for "realpath" in your application code. A single call to realpath() would cause that tree of stat calls you see. Also, you might be overflowing your realpath cache. PHP 5.2 is not using the cache very efficiently. This is fixed in 5.3. But try increasing your cache ttl and the size as well. eg.

realpath_cache_size = 256k realpath_cache_ttl = 7200
