ePolicy Orchestrator console become inaccessible in about 5-10 minutes after start

[User92479053]

I've updated ePO server from version 5.10u9 to u12 but after restart a problem occurred. In about 5-10 minutes after service startup console became inaccessible and browser reports timeout. Lots of Java exceptions in orion.log 2022-01-27T10:57:15,874 WARN [scheduler-TaskQueueEngine-thread-4] chainable.Chain - illegal state detected. status on completion should not have been IN_PROGRESS 2022-01-27T10:57:15,874 ERROR [scheduler-InternalTask-thread-8] engine.InternalTaskWrapper - Unhandled exception thrown by InternalTask task.queue.terminateLocalTasksPendingCancellation java.lang.OutOfMemoryError: Java heap space 2022-01-27T10:57:15,874 WARN [scheduler-TaskQueueEngine-thread-15] chainable.Chain - illegal state detected. status on completion should not have been IN_PROGRESS 2022-01-27T10:59:54,190 ERROR [https-jsse-nio-8443-Poller] server.OrionLifecycleListener - Exception caught in default Exception handler for : Thread[https-jsse-nio-8443-Poller,5,main] java.lang.OutOfMemoryError: Java heap space 2022-01-27T10:59:54,190 ERROR [scheduler-InternalTask-thread-15] engine.InternalTaskWrapper - Unhandled exception thrown by InternalTask task.queue.startNewTasksLocally java.lang.OutOfMemoryError: Java heap space 2022-01-27T10:59:55,565 ERROR [scheduler-InternalTask-thread-3] engine.InternalTaskWrapper - Unhandled exception thrown by InternalTask mne.tasks.processNetworkUnlocks java.lang.OutOfMemoryError: Java heap space 2022-01-27T11:01:03,861 WARN [scheduler-TaskQueueEngine-thread-13] chainable.Chain - illegal state detected. status on completion should not have been IN_PROGRESS 2022-01-27T11:01:03,861 ERROR [scheduler-InternalTask-thread-3] engine.InternalTaskWrapper - Unhandled exception thrown by InternalTask mne.tasks.processNetworkUnlocks java.

If issue occurred after installing update 12, the first thing I would do is to run the update again in repair mode.  Otherwise please open a ticket since you are getting out of memory errors in java.

Thamks for advice! Repair did not changed anything. I've made a rollback to u09. Works for now. I'll contact local techs for help with update later.

Thanks for your help!
