| we are encountering this error about 10 times a day which is quite critical, since it also breaks jobs which run for over an hour. As with OP, this occured after updating to 1.13.7. Before the upgrade, we had a lot of memory issues in OpenShift, therefore I would like to prevent having to roll back the version. One more thing that I noticed: Once this happens, it seems to affect more than one job. Also, after that there is always the exception later:
java.util.concurrent.RejectedExecutionException: Task okhttp3.RealCall$AsyncCall@3300fdcc rejected from java.util.concurrent.ThreadPoolExecutor@2e02dc25[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 258] {{ at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2063)}} {{ at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:830)}} {{ at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1379)}} {{ at okhttp3.Dispatcher.enqueue(Dispatcher.java:130)}} {{ at okhttp3.RealCall.enqueue(RealCall.java:100)}} {{ at okhttp3.internal.ws.RealWebSocket.connect(RealWebSocket.java:183)}} {{ at okhttp3.OkHttpClient.newWebSocket(OkHttpClient.java:436)}} {{ at io.fabric8.kubernetes.client.dsl.internal.PodOperationsImpl.exec(PodOperationsImpl.java:267)}} {{ at io.fabric8.kubernetes.client.dsl.internal.PodOperationsImpl.exec(PodOperationsImpl.java:61)}} {{ at org.csanchez.jenkins.plugins.kubernetes.pipeline.ContainerExecDecorator$1.doLaunch(ContainerExecDecorator.java:318)}} {{ at org.csanchez.jenkins.plugins.kubernetes.pipeline.ContainerExecDecorator$1.launch(ContainerExecDecorator.java:236)}}
So obviously, the error seems to not really affect the execution, but leads to the TRhreadPoll bein terminated. |
