WUProp (nci) client using 48% CPU in Linux kernel 3.11.0

Observation:
after upgrading to kernel 3.11.0 I observed the Data Collection version 4 4.11 continuously using 48% CPU on 2 cores of a 6 core CPU and 50% of 1 core on a 4 core CPU.

It does not behave like this on the 2 core CPUs

I have never seen this before, so I assume that it has something to do with the changes in linux kernel 3.11.

Suspend and resume returns to the same state.

Detach & re-attach returns to the same state.

It is consistently not (nci) any more with Kernel 3.11

removing WUProp from these machines immediately

Looks like my estimates are coming down again.
They exceeded 90 hours this morning, but now are back down to around 34 hours.

Hi Dirk.

You are correct that the WUProp project sends only one work unit per client at a time.

It is possible that the estimate baseline was reset when the latest client app was released on 29 Sept.
http://wuprop.boinc-af.org/apps.php
The original WUProp work units ran for much longer than the current length.

On the AMD Users forum you also observe that the estimate is getting longer.
I can confirm that I see the same thing on my clients also.
That behaviour is a puzzle.

There could be some other reason that the Admin may share with us?
