[Bug 458453] Re: beam.smp uses lots of CPU on desktopcouch contacts lookup
I upgraded my Ubuntu 10.04 system to 11.04 recently. I do not use
Evolution, Ubuntu One, or Gwibber or Weather. Yet I still find this
beam.smp process has burned 979 minutes of CPU since the last reboot 18
days ago -- apparently for no reason at all.
First, why is it getting started at all? ps ax --forest shows it's run
from /usr/bin/couchdb but there's no indication about why "Apache
CouchDB" is running at all. dpkg -S shows it's from the "couchdb-bin"
package. When I try to remove that package with "apt-get remove", it
also wants to remove desktopcouch and evolution-couchdb. I don't use
any of those things.
Aha, a clue: "apt-cache show evolution-couchdb" reports that "This package provides support for the Evolution mail and calendar program
to access CouchDB databases (http://couchdb.apache.org), a replication and
synchronization database of JSON documents, used by online services like
UbuntuOne at http://ubuntuone.com".
Great, so in Canonical's haste to use its Ubuntu distribution funnel to
drive revenues to its unrelated server cluster business, they stuck
everyone with this package that burns up CPU even when nobody uses it.
Clever.
Even more clever is that after I removed those three packages (couchdb-
bin, desktopcouch, evolution-couchdb), the damn beam.smp process IS
STILL RUNNING, burning up CPU! That's a packaging problem for sure.

Bug description:
Binary package hint: erlang
i'm having very slow automatic contacts lookup under karmic using
evolution 2.28.1-oubuntu1, erlang-base 1:13.b.1-dfsg-2ubuntu1, and
desktopcouch 0.4.4-0ubuntu1. CPU usage by beam.smp spikes up to about
80% and stays there for multiple seconds -- i'd say as long 20-30 --
before allowing input to continue. it renders the automatic contact
lookup actually counterproductive, not helpful.
would love to help squash thisbug, please advice where i should look
to try and help.
