I tried again with the 2.4.20 based kernel that Red Hat released
yesterday (2.4.20-13.7bigmem). The problem that I was seeing occurs
less frequently there, but it still happens.

I have attached a program which can reproduce this. If you run it
under 2.4.7 it fails instantly. If you use 2.4.20 it may take a
minute or so but it will also fail.

Thanks,

Jim

PS: Do you know if there is any way to work around this problem from
    within my program?
