I'm pretty sure I have some kind of memory leak. Here's what free
reports:
# free
total used free shared buffers cached
Mem: 1017876 955404 62472 0 128624 127944
-/+ buffers/cache: 698836 319040
Swap: 2040244 1652 2038592
Which suggests that I have 700MB "used".
But running ps:
# ps aux | head -n 1 | cut -c 1-100; ps aux | sort -n -r -k 4 | grep -v COMMAND | head -n 10

That is, the top ten processes have about 350MB resident. I don't
have a huge number of small processes or anything like that, so it
seems to me that about 300MB is "missing in action".
I'm running "2.6.18-1.2869.fc6 #1 SMP".
