Couchbase 4.1 Community Edition benchmark

Hi…
First of all thanks for the quick response.

I apologise regarding the server version it was my typo.
We are testing the Couchbase v4.0 CE.

I totally understand why we receive the "Temp failure"errors from the server, what I don’t understand is the Disk I\O behaviour.
Since I am not authorised to upload attachments what log files could shed some light on what is going on?

Thanks, Eli
