Glassfish - haute CPU sesg
Je suis en utilisant Glassfish 3.1.1 profil web dans la production envirnoment et il mange de trop de CPU.
Voici les paramètres de serveur: Windows Server 2008 R2 64 bits, Intel Xeon 8core @ 3,2 GHz, 8 go de ram.
Je suis à l'aide du JDK 1.7u2 64 bits. Glassfish: paramètres JVM:
<jvm-options>-XX:+UseCompressedOops</jvm-options>
<jvm-options>-Xmn1g</jvm-options>
<jvm-options>-Xss128k</jvm-options>
<jvm-options>-XX:+UseParallelOldGC</jvm-options>
<jvm-options>-XX:ParallelGCThreads=4</jvm-options>
<jvm-options>-Xmx3g</jvm-options>
<jvm-options>-XX:+DisableExplicitGC</jvm-options>
<jvm-options>-d64</jvm-options>
<jvm-options>-XX:PermSize=256m</jvm-options>
<jvm-options>-Xms3g</jvm-options>
<jvm-options>-XX:MaxPermSize=256m</jvm-options>
<jvm-options>-XX:+AggressiveHeap</jvm-options>
J'ai également régler certaines options en fonction de http://jfarcand.wordpress.com/2009/11/27/putting-glassfish-v3-in-production-essential-surviving-guide/
En cours d'exécution pour quelques heures ou 1 journée Glassfish utilisation de 15% à 40% de CPU, someties 90% et l'application ne marche pas répondre.

Edit: j'ai résolu le problème, il y a un bug dans Glassfish la compression gzip, je l'ai donc désactivé.
http://www.java.net/forum/topic/glassfish/glassfish/glassfish-301-gzip-problem-threads-apparently-spinning-100-cpu-use
Au lieu de cela je voudrais utiliser ce: http://www.servletsuite.com/servlets/gzipflt.htm pour compresser le contenu.

C'est apparemment un bug dans GlassFish 3.1.1 et 3.1.2. Le JIRA question pour elle contient les correctifs qui pourraient vous aider.
Cela peut être causé par une boucle infinie dans du code Java qui est référencé par une expression de la vue. Prendre une bande de roulement de vidage de votre serveur d'application lorsqu'il est en cours d'exécution et obtient ce problème, et la recherche de la problématique thread(s) comme par exemple votre
http-thread-pool-80(32)
ethttp-thread-pool-80(41)
-- si votre serveur d'application est de passer tout son temps sur un article, le code de votre application, il peut très bien être une boucle infinie (ou quelque chose d'autre que les causes qui l'exécution de code plus souvent qu'il ne le devrait).Nous avons eu un problème similaire, même si nous n'avons pas utiliser GZIP. Après un certain temps (et sous forte charge) nos journaux se remplissent avec
GRIZZLY0023: Interrupting idle Thread: http-thread-pool-28080(34)
Nous avons réussi à résoudre ce pour Glassfish 3.1.1 par la mise à niveau de grizzly à une version trouvée dans Glassfish 3.1.2.2. Lire plus à ce sujet à http://thumbtribe-it.blogspot.com/2012/10/grizzly0023.html
