Frontview crashes with heavy Bittorrent use

I have a ReadyNAS NV+ running 4.1.10.

If BitTorrent is really cranking, I lose Frontview, kinda like in this old post: http://www.readynas.com/forum/viewtopic.php?f=20&t=30290.

I could really use a clue since this requires a physical restart of the system to get Frontview running again. I know this system is old, but it's been pretty reliable -- if I could fix this, I'd be a happy puppy.

Here's an excerpt of my log (this is from httpd_errors.log). It starts with something -- I don't know what -- requesting an Apache restart.
