Reset the stats.

Is there some log that shows when a request hits the server and what job or program path a request takes? I'm trying to narrow down where the issue is.

You can turn up the logging level in the Apache server and check the
resulting log detail. Use the Admin console on port 2001/HTTPAdmin

You can also use this option to look at real time statistics.
