Re: Windows uname -o not supported.

[Josh McKenzie <jo...@datastax.com>]

That uname call is in there specifically to check if you're running from
cygwin and force a pidfile to be written for stop-server.bat if so; ctrl+c
functionality in mintty is inconsistent with its signal trapping across
both cygwin and Windows releases.

I wrote the PowerShell start-up scripts with the expectation that they
would be called from the .bat files so please give it a shot running the
batch files from a command-prompt or mintty terminal (or whatever your
terminal of choice is).  I'll look into what's broken when running directly
from PowerShell as this may be a more common use-case than I realized.

Along with that - are you running a 32-bit JVM or 64-bit here?

Xms3072M -Xmx3072M -Xmn768M

would lead to that kind of failure on a 32-bit JVM, though CASSANDRA-7353
<https://issues.apache.org/jira/browse/CASSANDRA-7353> should have resolved
that potential problem.  Might be related to the environment in PowerShell
rather than a command-prompt as well.
