[Bug 458453] Re: beam.smp uses lots of CPU on desktopcouch contacts lookup
It was apparently started by gwibber (perhaps because I briefly opened
the menu in the upper right corner of the Ubuntu Natty screen, which
seems to be a gwibber thing; I do not use social networking).
One possible problem is that the Erlang runtime is started with the -heart option, so it burns time whether or not any demands are placed on it. Is there a reason that the "desktop couchdb" instance needs a heartbeat? The heart process wakes up every 5
seconds, forever. And it demands that the main process wake up as frequently, too. This means that the CPU can never stop running for more than 5 seconds, even when the machine is "completely idle".
The main process seems to wake up every 10 minutes and write a few lines
to the logfiles. There is no apparent reason for this activity. I have
attached my logfile.

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.
