on windows server 3.0, failures to flush

When trying to run tests with the Java SDK, I have some flush operations. The server returns {error,{flush_wait_failed,['ns_1@127.0.0.1'],[]}} ...

There is only the default bucket, which is empty and is assigned 256MB of the cluster's RAM quota of 700MB (this is a dev workstation and I have lots of ram consumed by other tools, hence the low quotas).

When trying to flush from webconsole, I also often get an error : "Save request failed because of timeout."

Logs from a clean start of the server with only previous two issues reproducted will be attached.
