I have the same problem on my Feisty Fawn Server, running on a APC RS-1300 UPS (model BR1300LCD) connected by USB. Currently hald-addon-hid-ups eats 130 MB of memory, which I find excessive. It's the process that uses the most memory on my server right now, and the uptime is 7 days. I don't know if memory usage can/would go higher.
