(thread=Termination Thread, member=1): Write-behind thread timed out The following example log message demonstrates an action taken by the recovery mechanism: Actions that can be performed include: shutting down the cluster service, shutting down the JVM, and performing a custom action. Lastly, if the thread cannot be stopped, the recovery mechanism performs an action based on the configured failure policy. (thread=DistributedCache, member=1): Attempting recovery (due to soft The following example log message demonstrates a soft timeout message: Soft Timeout – The recovery mechanism first attempts to interrupt the thread just before the configured timeout is reached. The recovery mechanism is outlined below: The action to take can be configured and custom actions can be created if required. Corrective action is taken if the service guardian concludes that the thread is deadlocked. The service guardian's recovery mechanism uses a series of steps to determine if a thread is deadlocked. The list is not exhaustive and only provides the most common interfaces that are implemented by end users.Ĭom.Ĭom. Any processing in an implementation that exceeds the configured guardian timeout results in the service guardian attempting to recover the thread. Implementations of the following interfaces are executed by Coherence-owned threads. Interfaces That Are Executed By Coherence The service guardian does not have the ability to distinguish a deadlocked thread from a slow one. The term deadlock does not necessarily indicate a true deadlock a thread that does not issue a timely heartbeat may be executing a long running process or waiting on a slow resource.
