hi all, read thru the archives, esp thru thread: "PAE testing results ..." from circa May 03. I am getting a diffrent problem on a uniProc machine. with 5.2.1 and a stock PAE build. machine is stable and does not crash, but the big mem user job we want to submit to it, all these jobs die when they start using about 400MB of mem, swap doesn't activate. the user submitted job just core dumps. With previous 4.5 FBSD machines with the following kernel options compiled in (before PAE days) on same machine w/same 1.5GB of physical mem and plenty of swap, we'd get 1.2GB of usable mem for user job and rest would be kernel space. Job would run but not satisfactory, thought modern PAE would be a better bet. The kernel options we had used w/ 4.5 back then were: options MAXDSIZ="(1664*1024*1024)" options DFLDSIZ="(1664*1024*1024)" current Dmesg is listed below; Thanx in advance and pls reply also to me as i can't subscribe to the list at this point.
