I'll give the 2.4.20-2 patch a shot. If I'm still seeing the leak after applying it, I'll do my best to track it down (I already know it's somewhere in the fork() path, just based on the mean-time-before-death of a few test scripts I was playing with). I probably won't be able to isolate it down to a single line; I should, however, be able to capture enough information so that someone with far more awareness of the kernel's guts than I can track it down. :) Thanks again, - Dave
