Nils: You you asking that I stop posting here and continue this thread under the topic of "Client Errors when throtteling"(sic), following Message 102272?
Gary: Thanks for your informative post.
a. My PC is now un-hidden. Hope this helps.
b. I changed my preferences from CPU usage of 70% to 100% also, now I only allow computing overnight, and not at all when the computer is "idle". I also have preferences set to unload BOINC when it is not in use.
c. In message 102272 Nils said the latest development version was 6.10.29 which I guess you suggested be installed 'over the top' of my current version 6.10.18. However, I noticed that the most recent development version (as of 25 Feb) was 6.10.35. I thought before I install that version I should try to change my preferences to see if that resolves the problem.
I am not sure if this is good news or bad, but since I changed my preferences I have not seen any client errors in the log that I check daily. Also I see that eventually, credits are applied. The only thing I do not see (when computation is complete) is pending credits. That is, I see tasks are completed but credits don't show up for a few days and nothing is listed in pending credits.
If it would be of help I would be willing to go back to my previous preferences to see if the original problems re-occur. If you or Nils would like me to do this, what settings should I use and what version should I install that would give us the maximum amount of useful information.

It would help us to track down the problem (and potentially other participants, possibly of all BOINC projects) if you could
- install a recent development BOINC Core Client (any client from 6.10.29 on should have the necessary features),
- add the cc_config.xml file described in the other thread (I think you need to restart the client to recognize it) and
- restore your original computing settings (70% CPU usage)
I'm monitoring both threads, so feel free to post in either one.
4. Here are a few of the startup messages copied from the manager screen. NOTE Benchmark reports the number of CPU's as 2, which seems odd to me.

I need to analyze this a little bit more to find the actual problem, but it's definitely helpful!

If you want you can restore your previous compute settings (100% CPU overnight) to avoid the errors. The Client version and config file shouldn't harm. Please leave them in place, we may ask you for one or two more experiments like this again.
For the techs: It looks like that at some point there are multiple instances of the same application running in the same slot (i.e. writing to the same stderr file). One possible cause is that quitting an application (suspending a task by BOINC) may not work when it has threads suspended (for throtteling / CPU usage).
A fix at least for this possible issue has been checked into BOINC last night. I need to build new Apps with this and the we'll see if that actually fixes the problem. I'll do this ASAP, but there are a couple of higher priority things on my table that will probably occupy the the rest of this week.

Hi Bernd,
OK, I did the following:
1. created the following cc_config.xml (and added two items for fun ;-).
I put this file in my BIONIC folder.

90
2. I installed BOINC 6.10.35 (and verified that my cc-config file was not altered).
3. Changed by preferences back to 70% usage and allow to run when computer is idle (i.e., unused by me for more than 10 minutes).
Below is a copy of the global_preferences_override.xml file (which was in the same BOINC folder as cc-config file).
