I cranked the max memory usage down to 1.5 gigs, and my problems went away as well.
I don’t think that the ‘half way’ theory is true, however. I have been obsessively watching my Activity Monitor for the past two weeks (am I the only one who has become a AM junkie?), I have been noticing mine craps out at 1.9ish gigs. I am going to try to lock it down to 1.8 gigs to see if that is stable enough to use.
