Problème Leak Memory

**nightfall94** · 23/07/2010, 14h21

Salut,

J'ai installé Tomcat v6.0.26 avec Apache 2 sur une Debian. Java 1.6 est installé. Tomcat communique avec Apache via le proxy AJP.

J'ai déployé jtrac.war via la console Tomcat. Mais à ce moment, il me dit :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 ECHEC - L'application pour le chemin de contexte /jtrac n'a pas pu être démarrée.

Or lorsque je me rend sur l'URL de l'application, elle fonctionne. Lorsque je clique sur find leaks dans Diagnostics, il me réponds ceci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 The following web applications were stopped (reloaded, undeployed), but their classes from previous runs are still loaded in memory, thus causing a memory leak (use a profiler to confirm):
/jtrac
/jtrac

C'est donc une fuite mémoire. Un autre utilisateur a eu une erreur OutOfMemoryError PermGen Space. Cela veut donc dire que la JVM n'a pas assez de mémoire permanente.

Dans mon script de lancement de Tomcat, j'ai donc exporté une autre variable globale nommée JAVA_OPTS="-XX

ermSize=128m -XX:MaxPermSize=128m". Apparemment la taille de cette mémoire permanente est de base de 32m. J'ai redémarré Tomcat et impossible de démarrer l'application via la console Tomcat bien que jtrac soit toujours fonctionnelle

. Il y a donc toujours une fuite mémoire.

Quelqu'un aurait une idée sur la solution à employer ?

Merci d'avance

comme dit le message

"use a profiler to confirm"

en pratique, l'application a "mal" démarré, ça peut être une cause de memory leaks si l'application se base sur un arrêt "normal" pour nettoyer certains trucs (comme des threads), il n'y a pas donc à s'inquiéter outre mesure avant d'avoir réussi à démarrer puis arreter "proprement" l'application. Il faudrait donc regarder les logs de démarrage de ton jtrac pour savoir pourquoi il ne démarre pas (exception, erreur de configuration, ...?)

Salut et merci de ta réponse rapide. C'est vrai que c'est pas un très gros problème. Au moins l'application démarre.

Comme tu me l'a conseillé, j'ai regardé les logs de l'application jtrac. J'ai trouvé 5 fichiers de logs. Un seul traite du démarrage précise de l'application :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Par contre, je vois pas mal d'erreurs mais je vois pas ce que cela peut m'apporter pour résoudre le problème.

ben pourtant

java.sql.SQLException: The database is already in use by another process: org.hsqldb.persist.NIOLockFile@4b4e3b25[file =/root/.jtrac/db/jtrac.lck, exists=true, locked=false, valid=false, fl =null]: java.lang.Exception: checkHeartbeat(): lock file [/root/.jtrac/db/jtrac.lck] is presumably locked by another process.

il y a un fichier de lock (/root/.jtrac/db/jtrac.lck) qui laisse à supposer que la base de données en question est déjà en utilisation par un autre process donc

1) vérifier qu'aucun autre process n'utilise cette db
2) effacer le fichier lock sus mentionné
3) démarrer l'application

PS: un tomcat ne dois JAMAIS être démarré en root! C'est dangereux!

**nightfall94** · 23/07/2010, 16h06

Merci pour la petite faille de sécurité. Par contre, bizarrement le fichier /root/.jtrac/db/jtrac.lck n'existe pas :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
# ls /root/.jtrac/db/jtrac.lck
ls: ne peut acc?der /root/.jtrac/db/jtrac.lck: Aucun fichier ou r?pertoire de ce type

Mais j'ai trouvé le même dans une autre arborescence : /opt/apache-tomcat-6.0.26/temp/.jtrac/db/jtrac.lck

Je l'ai supprimé et j'ai redémarré Tomcat. Mais ça a rien changé en fait ...

**tchize_** · 23/07/2010, 18h19

tu n'aurais pas déployer deux instances de jtrac?

**nightfall94** · 23/07/2010, 19h25

En fait, à ce moment là, il y avait effectivement 2 instances jtrac. D'ailleurs sur le premier message d'erreur que j'ai édité, on voit bien qu'il marque deux fois /jtrac.

Mais j'ai tué Tomcat et donc Java. Du coup, quand je l'ai redémarré, il n'y avait plus qu'une seule instance. Par contre, c'est peut être un problème sur le fichier server.xml où je déclare l'hôte jtrac.x2p.fr. En effet, l'application jtrac doit répondre à cette URL. J'ai donc édité le fichier server.xml comme ceci :

<Host name="jtrac.x2p.fr" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">

<Context path="jtrac" docBase="" />

</Host>

Peut être qu'il y a une option qui manque ou une qui passe mal au niveau de la mémoire ou au niveau du bon déploiement de l'application.

**lunatix** · 24/07/2010, 11h15

Salut

le probleme mémoire n'a rien a voir avec ton probleme de demarrage. c'est juste une feature de tomcat qui te signale que lors d'un redeploiment, jtrac a une fuite mémoire, mais tu peux vivre avec sans soucis. (faut juste faire un start/stop de temps en temps). C'est une fonction de tomcat 7 qui a été backporté sur la branche tomcat 6 (depuis le 6.0.24 il me semble)

ton probleme de demarrage est bien lié a la base de données qui semble lockée

**nightfall94** · 26/07/2010, 14h32

Salut,
Finalement j'ai retrouvé un autre fichier jtrac.lck et je n'ai plus eu de problème. Merci pour la solution !!!
