Right. According to my notes from when I upgraded to 2.x, "18446744073709551615" means it's not set and that the default_vsz_limit will apply, which is 256 MB. To avoid the problem the original poster had, I used: default_vsz_limit = 1 G -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/
