Hi @Itay, Don’t have a fix for the issue. We need access to the box to do a little more digging. See dave’s note here: https://issues.couchbase.com/browse/MB-12775
Would you be able to give access to the box?
thanks

The box is busy doing other stuff
Was there a resolution to this issue? I’m facing the same thing on my Windows 2012 R2 Azure VM. The 2 processes, memcached and erl.exe. eat up 99% CPU with memcache spiking between 75% and 90% and erl.exe eating the remainder.
This was reported as https://issues.couchbase.com/browse/MB-14036, which is marked as fixed in 4.0.0. I believe 4.0.0 should be out in the near future.
Does 4.0.0 replaces 3.x.x ?
Or more specifically, should I upgrade from 3.0.1 CE to 4.0.0 or should I continue with the 3.x.x family ?
Hi @itay, 4.0 replaces 3.0 so you should upgrade when 4.0.0 is released. you will get improvements in performance by upgrading even if you are not using the new query language or indexing on the core data operations.

Will 4.0.0 new release be Community Edition ?
yes RC0 that has been published this past monday already has the release candidate for community edition and enterprise edition - couchbase.com/downloads

Just saw your answer.
I’m a bit afraid of using RC. Is it stable and bug free ?
3.0.1 CE is really giving me a bad time so I want to make sure that I’m making the right decisions, as upgrading the DB is a delicate operation.
Will the full 4.0.0 version be released CE as well ? Is there a time frame ?
Will 3.0.3 be CE soon ?
Is there a page where you publish your versions road map ?
Thanks,
Hi @itay, The timeline for 4.0 CE is early Oct. 4.0 includes all fixes in 3.0.3 version so I would recommend 4.0 CE when we are generally available. RC0 is not the finished version so we still have a few fixes we are adding before the targeted oct date.
thanks

Excellent
Does 4.0 requires any code modifications or is it plug and pray ?
4.0 is fully backward compatible unless you are using an un-documented method or you don’t know about the items we have here in the deprecation list (below),
http://developer.couchbase.com/documentation/server/4.0/release-notes/deprecated.html
Thanks,
I’m using .NET SDK so I guess there will be a specific version for 4.0 that will notify on any deprecated feature by not implementing them
Before migrating from 3.0.1 CE to 4.0.0 CE, where can I find a guide, manual, walkthru on how to do it correctly and successfully for the first time, on a running cluster ?
Thanks, Itay
Hi @itay, pls rehearse on another cluster first to make sure things work well. Also review the known issues list to ensure there isn’t anything that would impact your specific case.
You can find the upgrade manual here.
There are 3 upgrade strategies listed on the page and all 3 strategies mentioned here will work with CE.
Thanks

Thanks @cihangirb,
@jmorris, Should I upgrade from .NET SDK 2.1.3 to 2.2.1 before or after I upgrade to 4.0.0 CE ?
Thanks,
I’ll first upgrade the cluster and then the SDK
I read “the manual” but found nothing as to what I should do to upgrade.
What should I do once I download the new version ? Perhaps the answer is trivial, as in “just double click it” and everything should be taken care of.
Is there a step-by-step guide ?
you are right the instructions aren’t super clear here. http://developer.couchbase.com/documentation/server/4.0/install/upgrade-swap.html
Online Swap Rebalance is what I recommend you rehearse for your upgrade:
thanks
