It is memory-mapped I/O. I wouldn't worry about it.
BTW, Windows might not be the best choice to run Cassandra on. My
experience running Cassandra on Windows has not been positive one. We
no longer support Windows as our production platform.

The problem is that the system just freezes and nodes are dying. The system
becomes very unresponsive and it always happens when the shareable amount
of RAM reaches the total number of bytes in the system.
Is there something in Windows that I can tune in order to avoid this
behavior? I cannot

For performance reasons I switched to memory mapped IO. Is there a way to make
memory-mapped IO work in Windows?
Thanks!
