What I tried without result: * truncate the jboss_ejb_timer table (to remove existing) * remove all old @Schedule and add a new different timer * use @Resource TimerService instead of @Schedule * deployment using ** auto-deploy of zipped new war copied to $JBOSS_HOME/server/deployments/ ** call %jboss_bin%\jboss-cli.bat --connect controller=xxxxx:19990 --user=xxx --password=xxxx --command="deploy %war_path_1%%filename_1% --name=%package_name_1%.war --force" ** call mvn -q -f %package_name_1%\pom.xml wildfly:undeploy wildfly:deploy -Dwildfly.hostname=xxxxx -Dwildfly.password=xxxxxx restart or removing all timers allows to deploy again (for a time) {code} 2019-08-16 16:13:14,940 ERROR [org.jboss.msc.service.fail] MSC000001: Failed to start service jboss.deployment.unit."xxxxxxx.war".component.CronJobs.START: org.jboss.msc.service.Star tException in service jboss.deployment.unit."xxxxxxx.war".component.CronJobs.START: java.lang.IllegalStateException: Timer already cancelled. at org.jboss.as.ee.component.ComponentStartService$1.run(ComponentStartService.java:57) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1982) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1486) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1377) at java.lang.Thread.run(Thread.java:745) at org.jboss.threads.JBossThread.run(JBossThread.java:485) Caused by: java.lang.IllegalStateException: Timer already cancelled. at java.util.Timer.sched(Timer.java:397) at java.util.Timer.schedule(Timer.java:193) at org.jboss.as.ejb3.timerservice.TimerServiceImpl.scheduleTimeout(TimerServiceImpl.java:906) at org.jboss.as.ejb3.timerservice.TimerImpl.scheduleTimeout(TimerImpl.java:537) at org.jboss.as.ejb3.timerservice.TimerServiceImpl.startTimer(TimerServiceImpl.java:785) at org.jboss.as.ejb3.timerservice.TimerServiceImpl.restoreTimers(TimerServiceImpl.java:756) at org.jboss.as.ejb3.timerservice.TimerServiceImpl.activate(TimerServiceImpl.java:223) at org.jboss.as.ejb3.component.EJBComponent.init(EJBComponent.java:595) at org.jboss.as.ee.component.BasicComponent.start(BasicComponent.java:222) at org.jboss.as.ejb3.component.singleton.SingletonComponent.start(SingletonComponent.java:136) at org.jboss.as.ee.component.ComponentStartService$1.run(ComponentStartService.java:54) ... 8 more {code} As it happens in programming, I can't reproduce this at the moment.
