Ivan Kelly updated BOOKKEEPER-1030:
-----------------------------------
Labels: iktriage0 (was: )
> Better management of OutOfMemory errors
> ---------------------------------------
>
> Key: BOOKKEEPER-1030
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1030
> Project: Bookkeeper
> Issue Type: Wish
> Components: bookkeeper-server
> Affects Versions: 4.4.0
> Reporter: Enrico Olivelli
> Assignee: Enrico Olivelli
> Priority: Critical
> Labels: iktriage0
>
> Some bookie in production run OutOfMemory and the Bookie became really
> unstable.
> 17-01-24-13-11-42 Unexpected exception while writing 0@91465 :
> 17-01-24-13-11-42 java.lang.OutOfMemoryError: Java heap space
> That error was inside "WriteEntryProcessorV3" class in a catch (Throwable )
> clause.
> I'm running the Bookie inside a Java process not started with the "standard"
> scripts.
> My idea to handle this kind of errors is to add a global "System errors
> handler" to attach to any critical thread/operation and to pass any uncatched
> exception to it.
> In case of existing "catch Throwable" the code will call the system handler
> as well.
> Maybe we can provide a default implementation which only logs the error to
> the logger, a more invasive implementation which calls Runtime#halt.
> I'm trying in production with ExitOnOutOfMemoryError option but it does not
> give any chance to report the status of the JVM
