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:

and also some entries like

	at hudson.model.OneOffExecutor.run(OneOffExecutor.java:43)

We see theses issues since we updated the Priority Sorter Plugin to version 2.11 (from version 2.9)

Downgrading to version 2.9 seems to work fine!
