Subject [jira] [Commented] (CASSANDRA-7316) Windows: address potential JVM swapping
Date Mon, 06 Oct 2014 17:01:34 GMT


Joshua McKenzie commented on CASSANDRA-7316:

Updated branch [here|].  Added
check for automatically configured page file usage as well since it wasn't returning from
the other check, and suppressed convenience printing of size of page files if we got 0 back.

Since I can't reproduce the 0 page file size problem [~philipthompson], please let me know
how that part of it goes.  The MaximumSize is [supposed to come back as a uint32|]
so the current code *should* work with that.
