Since the last crash, I have had around 400 MB "free" RAM on dom0 (ie. free
or used by file buffering). I just noticed that the amount of "free" RAM
has dropped to 290 MB. I wonder if this is the same phenomenon that makes
the system run out of RAM.
I haven't done anything extraordinary on the system today - just copied some
data (a few hundred gigabytes) from one disk to another. Both disks are
behind an Areca RAID controller.
Here's what vmstat -m says now:

In use 101403K, total allocated 107199K; utilization 94.6%
If 107 MB is in use and 290 MB is "free", where's the rest of my 512 MB?
This is what top says:
Memory: 213M Act, 108M Inact, 19M Wired, 12M Exec, 280M File, 10M Free
Swap: 4096M Total, 4096M Free
I don't know how to read the numbers - if I add up all of them, I get over
640 MB (the same on my desktop system), so that can't be right.
Maybe there's a memory leak somewhere.. ?
