kryten2k35 on "[Plugin: WP-Filebase Download Manager] WP-Filebase seems to crash the Application Pool of my server"

Ever since installing this plugin, my server intermittently keeps going down for a few minutes while the Application Pool crashes and reboots, leaving me with a long load time or a 503 error.

I disabled the plugin, and lo'behold, the crashes happen. I'm gutted about this because I have just got it set up rather nicely and I really enjoy it's functionality.

Is there anything that can be suggested?

EDIT:

I might add that there are no errors in the debug, either.
