Joshua McKenzie commented on CASSANDRA-7316:
--------------------------------------------
Attempting to reproduce this on a vm since my primary machine is working fine.
Had philip dump out the Win32_PageFileSetting info coming back and the query
isn't giving him any data at all about maximumsize, and I'm not finding
anything about permissions restrictions giving back only partial info. If I
can't get to the bottom of this in a short time I'll just post a v3 that'll
mention it can't derive the page file size instead of printing 0, since the
important information we're looking for here is whether swap is enabled at all
or not.
