Hi, This happened to us before, on the same Couchbase version. We've been at 99% CPU usage even with a very light load.
We finally were able to pinpoint this to one of our view's reduce function. There's a limit to the reduce output - I'm not sure if this has been fixed in the latest version - but when we modified the view's reduce code, everything went back to normal. My guess is that with the erroneous view in place, we weren't getting errors when the view was emitting a small set of data, but became a problem when the data being returned became huge. You might want to check your views' reduce function, and see if there lies the culprit. For more details, see the link below. http://www.couchbase.com/issues/browse/DOC-26 Regards, Jed On Wed, Nov 26, 2014 at 5:48 PM, Marc Trudel <[email protected]> wrote: > I don't mind too much doing this, but I would love to understand what > causes the issue in the first place, if possible. > > P.S.
