In the interest of keeping people updated who might also be experiencing this issue, I've upgraded to a beta of 1.2.3, and things seem to be working alright. The issue appears to be an issue with PHP, as detailed in this link:

I'm not enough of a guru to do a spot PHP upgrade, so I figured moving to BSD 7.1 (as 1.2.3 is moving to it) would help with the issue. Whaddya know, it seems to be working so far. ;D
