      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:

      Apr 15, 2015 3:44:25 PM SEVERE hudson.triggers.SafeTimerTask run

      and also some entries like

      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!
