I upgraded the BOINC client today to 6.6.36 and now regardless of it being set to run only while my Mac is idle or being closed completely, dnetc runs constantly maxing one CPU core :-( Any idea what on earth is going on? I'm assuming this is connected to BOINC since that's the only change I've made on my system in the last couple days.

This is happening again after running BOINC. It's very rare, but very annoying when it does occur as quitting BOINC doesn't kill it. I have to use Activity Monitor to kill the dnetc process. Can I get some help with this issue, please? Does anyone know why this is still happening?

According to Wikipedia "dnetc" is:

distributed.net (or Distributed Computing Technologies, Inc. or DCTI) is a worldwide distributed computing effort that is attempting to solve large scale problems using otherwise idle CPU or GPU time. It is officially recognized as a non-profit organization under U.S. tax code 501(c)(3).

"dnetc" is the file name of the software application which users run to participate in any active distributed.net project. It is a command line program with an interface to configure it, available for a wide variety of platforms. distributed.net refers to the software application simply as the "client". As of May 2009[update], 32-bit Windows on Intel x86 is the most used configuration, with Linux on Intel x86 in second place, and Mac OS X on PowerPC in third place.

It isn't a BOINC supported project as far as I know. You may really have to look elsewhere on your system to see what installed it (including any search bars in browsers).

Well I've not installed any other distributed computing projects, nor do I use any 'browser search bars'. Googling dnetc and BOINC certainly generates some hits, though I admit I'm having trouble finding a direct linkage between the projects I run and this.

I got some unasked for and silently installed distributed search thingy through a streaming internet radio recorder a while back. I know that Winamp on Windows has some stupid option as well, which will be installed if you choose the "recommended" installation. I always choose Custom so I can see what it's trying to add extra on my system and even then some installers sneak things by.

But that second link I gave you will show how to get rid of it.
And else, if in extreme doubt, tell what projects you're attached to.

Well I've found out what it is: http://www.rechenkraft.net/yoyo/ which runs http://www.distributed.net/[/url]

In that case I was wrong - about it not running under BOINC - and it's a legitimate application.

You do know that BOINC itself doesn't do any science, that it is "just" a manager program for all the projects you choose to attach to? That those projects give out the science applications to run?

---

I do, it was just the co-incidence of updating BOINC Manager and then YoYo@home running that lead to me suspecting BOINC itself. What does bother me is BOINC Manager not enforcing the rules I set on when to run it's apps, or the reverse I suppose is more likely :-)

Try updating to BOINC 6.10.19 first, it has many fixes, including for the Mac.

Then make sure you didn't set the preferences through the web-site, but are (unknowingly) using the local preferences instead. When just going BOINC Manager->Advanced view->Advanced->Preferences and clicking OK without changing anything, you're immediately using those preferences, which override many of the web-site preferences. Click Clear to clear those preferences.

---

I'll give the latest version a try - I still had 6.6.36. Yup - I do have BOINC set to respect the preferences set on the website. Despite this dnetc continued running.

Thanks for your help :-)
