Thank you for your response What i'd like to be able to do on this 5.2.1 machine is run a user job that may take up 1.5GB of mem, i'd like it to start swapping which it doesn't do, nor does it panic, nor does it lock up. It stays responsive.
Taking what U said i recompiled the kernel as a non PAE build and included options maxusers 512 options MAXDSIZ="(1664*1024*1024)" options DFLDSIZ="(1664*1024*1024)" and i am now able to start the job and watch it go to about 1.2GB, actually 1.18GB, then either job stops or job coredumps, machine stays nice and responsive and stable. I have it configured w/ 2 large swap files on 2 diffrent spindles but the machine does not start swapping. The only error messages in the logs or dmesg is that this user job core dumped. What tunable parameters can i put into the next kernel build configuration to help me here? KVA_PAGES? setting maxusers to something else? I have a very small kernel requirement i want to maximize my user available space for this job..?
