Memory issue

[Mike McGrath]

What am I missing here?  This happened on db3 again -

             total       used       free     shared    buffers     cached
Mem:      18480632   18383512      97120          0      25968   17305332
-/+ buffers/cache:    1052212   17428420
Swap:      3145720    3145720          0


1) This box was swapping out like crazy.

2) All swap was full

3) oomkiller didn't start

4) Load went up a little bit, topped out at 3

5) no issues with the box at all, has postgres on it, kept running, wasn't
slow, box was completely responsive.

6) It's done this before, and aside from nagios alerting us the swap was
full, not had any issues with the box.

7) vm.swappiness = 60 which IIRC is the default
