¿Interbloqueo de integración de primavera utilizando Aggregator + MessageStoreReaper + Redis?

pero este mensaje es demasiado largo para publicar. Continúo con la publicación original

Actualicé a la última versión de Java 7 1.7.0_60-b19 pero el problema todavía está allí.

Hice otro volcado de hebras y encontré el mismo problema: todos los DefaultMessageListenerContainers (recuento 20) están bloqueados por taskScheduler (entityScheduler-3) en la invocación de bloqueo de AbstractCorrelatingMessageHandler.

Aquí está la configuración del programador y agregador:

<task:scheduled-tasks scheduler="entityScheduler">
<task:scheduled ref="entityReaperBean" method="run" fixed-rate="${entity.aggregator.timeout}" />
</task:scheduled-tasks>
<bean id="entityReaperBean" class="org.springframework.integration.store.MessageGroupStoreReaper">
<property name="messageGroupStore" ref="entityAggregatorRedisMessageStore" />
<property name="timeout" value="${entity.aggregator.reaper.timeout}" />
</bean>
<bean id="entityAggregatorRedisMessageStore"
class="org.springframework.integration.redis.store.RedisMessageStore">
<constructor-arg ref="entityRedisConnectionFactory" />
</bean>
<int:aggregator id="entityAggregator" send-partial-result-on-expiry="true"
release-strategy-expression="size() >= ${transactions-receiver.batch_size}" correlation-strategy-expression="payload.entityCode"
expire-groups-upon-completion="true" message-store="entityAggregatorRedisMessageStore" />

Aquí está la sección de volcado de hilo:

Locked ownable synchronizers:
- None

¿Es posible que, por alguna razón, el método handleMessageInternal de AbstractCorrelatingMessageHandler no se desbloquee? Uso un almacén de mensajes de Redis y veo que MsgStoreReaper también usa un bloqueo. ¿Podría ser eso un problema?

muchas gracias por su ayuda aquí! Saludos a Guzman

ACTUALIZAR:

Encontré este mensaje en el registro:

 2014-07-23 22:47:26,967 ERROR TaskUtils$LoggingErrorHandler:95 - Unexpected error occurred in scheduled task.
2014-07-23 22:47:26,968 ERROR RedisMessageStore:122 - Exception in expiry callback
2014-07-23 22:47:26,971 ERROR TaskUtils$LoggingErrorHandler:95 - Unexpected error occurred in scheduled task.

pero no hay excepción ni stacktrace. ¿El error TaskUtils te dice algo?

Answer 1

En realidad, veo un lugar ...

 finally {
if (removeGroup) {
this.remove(group);
}
lock.unlock();
}

... si el almacén de mensajes arroja una excepción durante la eliminación, omitiríamos el desbloqueo, ¿ves algo en el registro?
