That seems sensible to me. 2^64 bytes is 18446744073709551616 (18.45EB), so the number shown is (2^64 - 1). As a *limit* for a 64-bit program, that seems about as close to "no limit" as you're going to get :) > > To avoid the problem the original poster had, I used: > > default_vsz_limit = 1 G > > -- > Robert L Mathews, Tiger Technologies, http://www.tigertech.net/
