I=E2=80=99m inclined to say that it=E2=80=99s best to remove the limits altogether and just work with the default. If you need different default, add them to your kernel configuration. Set MAXTSIZ, DFLDSIZ, MAXDSIZ, DFLSSIZ and MAXSSIZ accordingly. Since you lower maxdsiz and maxssiz from 1G to 512M, you can safely leave them as is (unless you tend to have runaway processes :-) You increase maxssiz from 256M to 512M, which you probably want to keep doing to make sure you can run the same set of processes as you do now. At this point in time, the only fix I=E2=80=99m willing to make is for the size of the array that holds relocations. If it made things better, I=E2=80=99ll commit it. If it didn=E2=80=99t, = then I=E2=80=99m not going to commit it. Anything more involved will take more time than I=E2=80=99m willing to put into ia64 at this time...
