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 Timer task hudson.model.Queue$MaintainTask@5d00189f failed java.lang.NullPointerException at jenkins.advancedqueue.sorter.AdvancedQueueSorter$2.compare(AdvancedQueueSorter.java:99) at jenkins.advancedqueue.sorter.AdvancedQueueSorter$2.compare(AdvancedQueueSorter.java:81) at java.util.TimSort.countRunAndMakeAscending(TimSort.java:329) at java.util.TimSort.sort(TimSort.java:189) at java.util.TimSort.sort(TimSort.java:173) at java.util.Arrays.sort(Arrays.java:659) at java.util.Collections.sort(Collections.java:217) at jenkins.advancedqueue.sorter.AdvancedQueueSorter.sortBuildableItems(AdvancedQueueSorter.java:81) at hudson.model.Queue.maintain(Queue.java:1135) at hudson.model.Queue$MaintainTask.doRun(Queue.java:2197) at hudson.triggers.SafeTimerTask.run(SafeTimerTask.java:54) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:304) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:178) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Feed
and also some entries like
java.lang.NullPointerException at jenkins.advancedqueue.sorter.AdvancedQueueSorter.onLeft(AdvancedQueueSorter.java:157) at jenkins.advancedqueue.sorter.AdvancedQueueSorterQueueListener.onLeft(AdvancedQueueSorterQueueListener.java:47) at hudson.model.Queue$LeftItem.enter(Queue.java:2087) at hudson.model.Queue.onStartExecuting(Queue.java:924) at hudson.model.Executor.run(Executor.java:209) 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!
