Consumo excesivo de JAVA al cabo de 10 días

Yo tengo utilizado con éxito el Recolector de basura G1GC

Hola ‌

Un LDAP grande puede derivar en ese tipo de problemas de cache, sobre todo si se tiene una estrategia de full sync en vez de diferencial sync, pero la frecuencia (diaria) e intervalo temporal no corresponde. Si el WARNING ocurriese todos los días a las 00:00 horas...

Saludos.

Buenos días,

Ya por probar que no quede...Pero he deshabilitado la sincronización LDAP y el problema persiste...a si que a seguir buscando...

Muchas gracias!

Buenos días,

Por otro lado, estuve mirando con Cristina posibles problemas que tuviera en la config. Lo único que fue más raro ha sido que tenía la auditoria habilitada. La he desactivado, pero sigo viendo el error de caché el cual es continuo ha si que de eso tampoco es :-(

Por otro lado, revisando más en detalle los logs de catalina.out veo algunos errores como estos...voy a mirar si por aquí pudiera venir el problema:

Hola:

La auditoría es mejor desactivarla si tienes problemas de rendimiento. 

También puedes probar a desactivar el suggester de SOLR que está relacionado con los WARNING de WFSTInputIterator* y que te habrá creado unos archivos temporales importantes en $ALF_HOME/tomcat/temp/*....

Para ello suggester.enabled=false en /opt/alfresco52g/solr4/workspace-SpacesStore/conf/solrcore.properties (y reiniciar alfresco)

Saludos.

[cristinamr]

Una pena que no vengan por ahí los tiros Bueno vamos a intentarlo por otro lado:

¿Y si probados a poner el log a debug? Podrías poner en alfresco/tomcat/shared/classes/alfresco/extension/custo-log4j.properties (o similar) esto:

log4j.logger.org.alfresco.repo.cache.TransactionalCache=debug

Reinicias y a ver si nos dan mas detalles los logs /alfresco.log y catalina.out)

Por cierto ¿conseguiste replicar el problema en otro entorno?

Por cierto lo que comenta César deberías hacerlo para no cargar más el sistema.

Cris.

Buenas tardes,

En el otro entorno de pruebas (es exactamente el mismo entorno pero sin usuarios utilizándolo) con la auditoria activada pasa exactamente lo mismo:

2017-02-09 11:15:33,324 WARN [org.alfresco.userToAuthorityTransactionalCache] [http-apr-8080-exec-2] Transactional update cache 'org.alfresco.userToAuthorityTransactionalCache' is full (100).

A si que esto es preocupante porque no hay usuarios haciendo nada...

Por el lado de debug, lo probaré y os iré diciendo lo que va apareciendo.

Muchas gracias!

Un saludo!

Buenos días a todos!

Ya he puesto el debug en el log y he obtenido el siguiente mensaje :

¿Os dice algo a alguno de vosotros o solo es un log informativo?

Hola Ruben:

IMO, que una caché se llene puede degenerar en un problema de rendimiento pero no tiene por qué ser así. Si esto fuese así, los momentos en los que se pierde el servicio serían relativamente claros. ¿ Cuanto tiempo pasa desde el WARNING hasta que se pierde el servicio ? Por otro lado, desde la última versión del módulo de OOTB Support Tools se pueden borrar/vaciar las caches en caliente.

Es más significativo un jstack en el momento que notas una pérdida de rendimiento, porque permite ver los hilos de ejecución. Entre los hilos que estén esperando desde hace un tiempo, estarán los "procesos" que están dando guerra en tu sistema.

Saludos.

[rublape]

Hola César,

Ese mensaje está apareciendo continuamente, pero el problema rendimiento suele ocurrir cuando lleva unas dos semanas (aprox) el servicio Alfresco sin reiniciarse... Al ver estas alarmas en el log estabamos intentando ver si el fallo de rendimiento es producido por la caché.

Por otro lado, en cuanto falle de nuevo Alfresco adjuntaré los resultados de jstack a ver si arroja algo más de información.

Un saludo!

Rubén
