Unlikely, but any Forbidden error should be logged in access_log with  
the IP address so that would be a place to start.

It would also be useful to do a run-time leaks check; on Mac OS X I'd  
just recommend using the "leaks" tool for this, but I'm not sure if  
similar tools are available to dynamically check a process for leaked  
memory without stopping it...
