This line is superfluous and can safely be removed. The PHP memory limit is not needed, if it is higher anyway (which likely is the case today).

The part "Protect against web entry" must stay. $wgSecretKey also must be set.

As for the session_save_path I can't really tell. It at least looks srange to set it to "tmp" without any slash at the beginning. Can you test, if that in facts makes a subfolder of the current execution folder the temp dir?

Anyway, all this will most likely not solve the original issues.
