Managers,

 Please excuse me if this a FAQ. One of our
 3000/600 Alpha's complains about not having
 enough swap space whenever a cpu-intensive
 process is running (even though the processes
 should fit into memory). This machine has
 160 MB memory and 320 MB swap space. Here's
 the output of "swapon -s":
  

Swap partition /dev/rz3b (default swap):
    Allocated space: 40960 pages (320MB)
    In-use space: 21268 pages ( 51%)
    Free space: 19692 pages ( 48%)


Total swap allocation:
    Allocated space: 40960 pages (320MB)
    Reserved space: 36000 pages ( 87%)
    In-use space: 21268 pages ( 51%)
    Available space: 4960 pages ( 12%)

 I'm confused about the reserved space. What
 reserves this space, the system or processes?
 Any help would be greatly appreciated. I will
 send a summary.

Thanks,
Steve
