Unfortunately the 'cp vmcore /var/tmp' crashed due to out of memory. :( The memory on the regular kernel showed: [root@holism tmp]# free total used free shared buffers cached Mem: 805312 443520 361792 0 36288 295936 -/+ buffers/cache: 111296 694016 Swap: 6143968 0 6143968 and the memory on the crash dump kernel showed: [root@holism tmp]# free total used free shared buffers cached Mem: 47776 45952 1824 0 1056 11856 -/+ buffers/cache: 33040 14736 Swap: 6143968 54720 6089248 It came down from 805312 k to 47776 k with only 1824 free. How much memory do i need to do a 'cp /proc/vmcore /var/tmp'? Thanks, - jay
