Description:

Hi,
Our Jenkins server seems to get locked at some point in time.
Many Jobs are in _starvation_, waiting for nodes with certain _labels_/_label combinations_.
(i.e. _Waiting for next available executor on ..._)
The log shows a lot of these entries:

We see theses issues since we updated the [Priority Sorter Plugin|https://wiki.jenkins-ci.org/display/JENKINS/Priority+Sorter+Plugin] to _version 2.11_ (from _version 2.9_)
Downgrading to _version 2.9_ seems to work fine!
