Hi Andy,
Sorry that wasn't an exact transcript. I was actually doing...
perl -e 'print 1 x 600000000' > /mnt/r0/file0
which fills the drive and then stops. This seems to work as long as the
total number of 1's I write to ram is less than 40% of total memory I
have (regardless of how large the ramdisks are or how many I create).
I have created 10MB and 100MB ramdisks which seem to work fine. Writing
and rewriting work as expected (and fast!). It's only when I create more
and larger drives do I encounter problems.

In the example given, you seem to be copying 600MB of '1's to the
mountpoint? (I don't know Perl). Maybe things would go differently if
you sent this to a file on the mountpoint... eg
dd if=/dev/zero of=/mnt/r0/testfile bs=1024 count=450000
At some point the machine seems to just freeze and crash. It responds to
ping but is unresponsive to ssh or other input and must be powercycled.
I know there is enough free memory for this. It seems to happen when I
fill just under half of the memory I should have allocated... Allocating
less (< 40%) seems to work just fine.
Hm I would try a single 128 Ram drive and see if I could fill it up, if
the first idea didn't help.
