TASK DESCRIPTION As as a maintainer of a service running on top of the JVM I want the JVM to rapidly quit if it enters a gc death spiral so that the service increase its availability. The default heuristics used by the JVM to kill itself (`-XX:+ExitOnOutOfMemoryError`) are too conservative to make them useful for real production use cases. jvmquake <https://github.com/Netflix-Skunkworks/jvmquake> seems to circumvant these problems by allowing more flexible heuristics to detect when the JVM will be stuck in a death spiral. This approach might be useful for several services: - blazegraph sometimes stuck in a death spiral certainly triggered by a bad query - cloudelastic sometimes misbehaving because of the GC AC: - Blazegraph rapidly restarts before entering a GC death spiral TASK DETAIL https://phabricator.wikimedia.org/T293862 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: dcausse Cc: Aklapper, dcausse, MPhamWMF, CBogen, Namenlos314, Gq86, Lucas_Werkmeister_WMDE, EBjune, merbst, Jonas, Xmlizer, jkroll, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles
