Login page blank with APC enabled

I have APC enabled with the below settings. Everything seems to work ok, with the excpetion of the login/login page which comes up blank or displays a 500 error depending on the browser. I am using APC 3.1.9 and php 5.3.3. If I turn off APC it works correctly but the site becomes considerably slower. There are no error logs in the XF admin area

Is there a problem with my settings or is there a way I can filter login/login to exclude it from being cached in APC. If so how do I do that?

A 500 error is very generic. Is it recorded in the server logs? Ideally your logs will have more information about the error.

I don't know of any way to exclude that specific location.

there is nothing specific that I can see that relates to the issue
