Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Tue, 02 Mar 2010 07:17:17 GMT

Hello,J'ai besoin de votre aide. Sur un serveur qui est fonctionnel depuis plus d'un mois, Alfresco utilise, depuis quelques jours, la CPU à 100%. Je ne sais pas trop comment résoudre ce problème. J'utilise Alfresco 32.r2 (2440) avec Mysql (5.0.77 Source distribution)J'ai effectué deux jstack (aperç

pas mal de problème dans votre install apparemment.. mauvaise configuration cifs, problème d'accès à la base (est elle down ? ) …

cet outil vous permet de déterminer l'utilisation cpu des threads les plus consommatrices de cpu, ça vous donnera sans doute plus d'infos sur la cause : http://weblogs.java.net/blog/brucechapman/archive/2008/03/hot_threads.html

Merci bien 🙂

La base fonctionne… Je n'ai plus eu le message d'erreur précédent (avec NetBIOSException et mysql) depuis mon redémarrage (il y a 2 jours). La CPU continue a chauffer la pièce…

Voici ma config pour le cifs (/opt/Alfresco/tomcat/shared/classes/alfresco-global.properties). Elle fonctionne bien sur d'autres installations (RHEL 5.2, ici on est avec une centos 5.4)…

# CIFS
cifs.enabled=true
cifs.ServerName=${localname}
cifs.domain=xxxxx
cifs.hostanounce=true

cifs.broadcast=0.0.0.0
cifs.tcpipSMB.port=1445
cifs.ipv6.enabled=false
cifs.netBIOSSMB.namePort=1137
cifs.netBIOSSMB.datagramPort=1138
cifs.netBIOSSMB.sessionPort=1139‍‍‍‍‍‍‍‍‍‍‍‍

J'ai tenté d'utiliser le programme de votre lien, mais comme indiqué dans un commentaire (le premier), cela ne fonctionne pas directement avec Linux. J'ai tenté aussi un "top -H" puis jstack du processus qui utilise la CPU, mais cela n'a pas fonctionné.

[root@localhost lib]# /usr/java/jdk1.6.0_16/bin/java -classpath /usr/java/jdk1.6.0_16/lib/ -jar /media/lienVersPartage/HotThread.jar 25744

J'ai essayé avec et sans spécifier le classpath. Le tools.jar (contenant com.sun.tools.attach.VirtualMachine) est présent dans /usr/java/jdk1.6.0_16/lib/

La config du CIFS semble-t-elle être erronée :?:
Avez-vous la bonne commande pour lancer le HotThread sous Linux :?:
Merci

Fonctionne très bien sous Linux si.
Voici un exemple :

java -classpath $JAVA_HOME/lib/tools.jar:HotThreads.jar hotthread.Main 10454‍

ou dans votre cas si JAVA_HOME n'est pas défini :

java -classpath/usr/java/jdk1.6.0_16/lib/tools.jar:HotThreads.jar hotthread.Main 10454‍

Merci pour la commande.
Voici mon résultat :

il semble donc bien que pas mal de temps soit passé dans pdfbox ….utilisez vous des pdf très gros ? injectez vous beaucoup de pdf simultanément ?
quelle est la conf matérielle ?

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

Il y a environ 12 pdfs par jour (moyenne chacun pèse 2 megabytes, provenant d'un scanner Scan Station Kodak en 200 dpi noir/blanc OCR) répartit sur la journée contenant chacun une dizaine de pages. Ces PDFs sont ensuite découpés en 1-3 nouveaux PDF's. Le traitement pour les découpés en assez vite fait (max quelques minutes en fonction du nombre de pages).

Il y a donc en tout environ 40 pdf par jour du lundi au vendredi. Il n'y a pas d'envois simultanés (cependant, lors du découpage, plusieurs fichiers sont créés très rapidement).

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

rguinot — Wed, 03 Mar 2010 13:31:39 GMT

quand vous dites alf_data est sur le NAS, est ce que vous indexes Lucene sont stockés en local ou sur le NAS ?

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Wed, 03 Mar 2010 13:41:05 GMT

Les indexes Lucene sont stockés sur le NAS.

L'attente d'accès disque ferait-il tourner en rond la création des indexes?
Me conseillez-vous de transférer le lucene index en local ?

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

rguinot — Wed, 03 Mar 2010 13:53:09 GMT

Oui je recommande très fortement de mettre les indexes en local, propriété dir.indexes. C'est probablement la cause de pas mal de problèmes.
Vous pouvez voir si vous brulez du CPU en attente d'io avec la colonne "wa" de vmstat (kernel 2.6 minimum)

verifiez également la config de la base de données , voir notamment http://www.mysqlperformanceblog.com/2007/11/01/innodb-performance-optimization-basics/

et la config de la JVM, voir notamment : http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Thu, 04 Mar 2010 07:39:36 GMT

Demain après-midi je vais transférer tout le alf_data et la base sur le disque local.

J'ai remarqué qu'avec un alf_stop.sh, Java tournait toujours. Ai je d'autre choix que de killer java pour l'arrêter :?:
Mysql pourrait être un ralentissement (comme vous me l'avez suggéré), ai je un moyen de savoir si alfresco est en attente sur mysql :?: Cela n'influencerai que lors de l'indexage en background car quand on ajoute des fichiers, ou demande de l'information, alfresco répond immédiatement.

Merci bien 🙂

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

rguinot — Thu, 04 Mar 2010 09:24:18 GMT

pour savoir ce sur quoi il bloque, un thread dump vous le dira.
avant de corriger la config mysql / jvm, commencez en effet par mettre les indexes en local.
d'autre part, sur votre serveur avec 1 CPU monocore 2.3 Ghz, 2GB RAM, est-ce vraiment nécessaire de mettre Alfresco dans une machine virtuelle ? votre serveur héberge-t-il d'autres VM ?

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Thu, 04 Mar 2010 09:51:27 GMT

la config mentionnée plus haut était celle de la VM. Il y a effectivement plusieurs VM sur le même serveur.

Merci.

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Fri, 05 Mar 2010 15:33:24 GMT

J'ai été contraint de killer java pour éteindre Alfresco.

Le alf_data (dont l'indexe) et la base Mysql sont sur un deuxième disque dans la machine virtuelle (directement lié au serveur).

Cela fait plus d'une heure que le serveur fonctionne et la CPU est toujours à 100%. Il lui faut peut-être un peu de temps pour finir ces tâches… Je redonne des news lundi matin.

Merci

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Mon, 08 Mar 2010 10:36:44 GMT

J'ai copié les données sur une autre GED. En redémarrant, l'indexation travaille aussi (utilisation de la CPU à 100%). Cela me permet de faire des tests.

Pour commencer, je vais changer les arguments de démarrage :

/usr/java/jdk1.6.0_17/bin/java -server -Xcomp -Xbatch -Xss1M -Xms1G -Xmx1500m -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewSize=512m -XX:MaxPermSize=128M -XX:CMSInitiatingOccupancyFraction=80 -Dalfresco.home=/opt/Alfresco -Dcom.sun.management.jmxremote -XX:CompileCommand=exclude,org/apache/lucene/index/IndexReader$1,doBody -XX:CompileCommand=exclude,org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger,mergeIndexes -XX:CompileCommand=exclude,org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger,mergeDeletions -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/opt/Alfresco/tomcat/conf/logging.properties -Djava.endorsed.dirs=/opt/Alfresco/tomcat/endorsed -classpath :/opt/Alfresco/tomcat/bin/bootstrap.jar -Dcatalina.base=/opt/Alfresco/tomcat -Dcatalina.home=/opt/Alfresco/tomcat -Djava.io.tmpdir=/opt/Alfresco/tomcat/temp org.apache.catalina.startup.Bootstrap start‍

La machine dipose de 2 GB de Ram.
http://wiki.alfresco.com/wiki/Repository_Hardware

Je vais laisser tourner 1 jour. Si cela n'a pas d'impact, je vais modifier ensuite la configuration de Mysql.

Re: Alfresco utilise la CPU à 100% depuis plusieurs jours

dranakan — Tue, 09 Mar 2010 08:50:17 GMT

La CPU tourne toujours à fond… bien qu'aucun nouveau document ait été ajouté. Je vais laisser tourner encore moment.

Je ne pense pas que Mysql soit le ralentissement car si on regarde les processus, on voit qu'il ne travaille pas :

mysqladmin processlist -u root -p

Serait-ce possible que l'indexage tourne en rond sur un document ? Est-il possible de savoir où il en est ? Par exemple qu'il dise j'ai indexé 456 fichiers sur 12'345.
Si quelqu'un a une idée…

Merci bien 🙂

Hello,

Suivant les conseils de rguinot, j'ai amélioré la configuration de mysql (attention, je suis pas un expert en Mysql, j'ai juste incrémenté quelques champs).

/etc/my.cnf

[mysqld]
datadir=/backup/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /backup/mysql/
innodb_data_file_path = ibdata1:10M:autoextend

# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 512M
innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 128M ERROR IN Alfresco WHEN UNCOMMENT :  Failed to dump normalized, pre-upgrade schema to file.  Error: Incorrect information in file: './alfresco/JBPM_ACTION.frm'
innodb_log_buffer_size = 256M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
innodb_thread_concurrency=8
innodb_flush_method=O_DIRECT
transaction-isolation=READ-COMMITTED

[mysqld_safe]

Je note aussi que la CPU commence à s'affoler, après démarrage, uniquement quand j'envoie un document (peut importe sa provenance (PDF du scanner, PDF générer depuis Word, Document Word, …). Alfresco indique :

Après ceci, CPU à 100%, mais le serveur est parfaitement fonctionnel.

Besoin d'aide…
