Hello Mike...

It (at least) seems like that the fact that this is a Intel Rapid
Storage RAID10 does play a role after all.

I did several tests this morning, after I finally managed to get
another disk hooked up via USB3 (the best I could do for now).

I tried dm-crypt w/ a single partition and with a Linux s/w RAID1 and
RAID10. Unfortunately the RAID tests were done with several partitions
that were on the same disk since that is all I have for testing.

No matter what I did, I could not get to the point where all memory
got exhausted... not even close.

So with all tests I have done over the last couple of days, the only
one were I could always hit this issue was with my original RAID10
that is a Intel Rapid Storage RAID -- and hooked up to the internal
SATA3 ports instead of the USB3 port (which I hope makes no huge
difference for this issue).

I will post to the linux raid list in a few moments and cc' this list
as well.

Thanks again for the help thus far,
Matthias
