[JBoss JIRA] (WFLY-12167) Memory leak in metrics in standalone-ha configuration

by Jeff Mesnil (Jira)

[ https://issues.jboss.org/browse/WFLY-12167?page=com.atlassian.jira.plugin... ] Jeff Mesnil commented on WFLY-12167: ------------------------------------ I investigated it a bit and the issue seems to be related to the clustering component. When a /metrics HTTP request is queried, the metrics subsystem will invoke the :read-attribute for the clustering resources (e.g. thread-pool-min-threads on the channel=ee/protocol=UDP resource). Since the returned value is undefined, the metrics subsystem will ignore this attribute. However comparing heap dumps between /metrics queries reveals a significant increase of ServiceName and ServiceRegistrationImpl instances (that are not GCed). It seems the issue is related to https://github.com/wildfly/wildfly/blob/master/clustering/service/src/mai... (as the service names are identified with UUID). It seems that the ServiceRegistrationImpl created by the one-off service is not been properly removed from the Map in org.jboss.msc.service.ServiceContainerImpl#getOrCreateRegistration [~pferraro] I'm assigning this issue to you so that you can double check if the code in ServiceSupplier is correct or if the leak comes below from MSC. [~brian.stansberry] [~jamezp] I'm raising the priority to blocker as this issue will eventually lead to memory exhaustion when the app server metrics are queried. Depending on the time scale, we also have a workaround: * explicitly state the subsystems that expose metrics (now it is set to the * wildcard to expose metrics from all subsystems) so that groups metrics are not queried at all > Memory leak in metrics in standalone-ha configuration > ----------------------------------------------------- > > Key: WFLY-12167 > URL: https://issues.jboss.org/browse/WFLY-12167 > Project: WildFly > Issue Type: Bug > Components: MP Metrics > Affects Versions: 16.0.0.Final > Reporter: Bernd Stolle > Assignee: Jeff Mesnil > Priority: Major > Labels: memoryleak > Attachments: Screenshot 2019-06-06 at 11.07.00.png > > > When started in standalone HA configuration every request to the recently added metrics endpoint ({{<management-if>:9990/metrics}}) lead to an increase in memory consumption until the JVM is slowed down significantly by GC to a point where even the requests to {{/health}} fail within a reasonable timeout (2s) and untlimately lead to OOM. > The same issue does not occur when WildFly is started in the default standalone configuration (non HA). > I can provide a (compressed) heap dump if required. -- This message was sent by Atlassian Jira (v7.12.1#712002)

[JBoss JIRA] (DROOLS-4137) KIE Maven Plugin Fails to Load Dependencies for KieBase when Serializing KieBase During Build

by Mario Fusco (Jira)

[ https://issues.jboss.org/browse/DROOLS-4137?page=com.atlassian.jira.plugi... ] Mario Fusco commented on DROOLS-4137: ------------------------------------- I'm not sure why you're referring to a feature that is mentioned in the "Android Integration" chapter, that clearly is not your case. However I agree that docs is very old and outdated and we should fix it. In Drools 7 we replaced any need for serialization with what we called the executable model http://docs.jboss.org/drools/release/7.22.0.Final/drools-docs/html_single... We are also using it to implement the drools integration with Quarkus, see https://developers.redhat.com/blog/2019/03/14/quarking-drools-how-we-turn... I strongly suggest you to compile the kjar with the executable model (this will become the default in one of the next drools releases) and this should fit pretty well with usage of drools in a serverless environment. > KIE Maven Plugin Fails to Load Dependencies for KieBase when Serializing KieBase During Build > --------------------------------------------------------------------------------------------- > > Key: DROOLS-4137 > URL: https://issues.jboss.org/browse/DROOLS-4137 > Project: Drools > Issue Type: Bug > Affects Versions: 7.22.0.Final > Reporter: Justin Holmes > Assignee: Mario Fusco > Priority: Major > > I would like to have kie-maven-plugin build the KJar with a serialized KieBase so that it takes less time to boot strap drools.

It probably needs updates. If we can get help to get the build working / bug fixed, we would be happy to submit a doc fix. > We are trying to use drools in a severless environment (though not quite ready for Quarkus). If we are unable to use this build feature, we may be unable to use drools. -- This message was sent by Atlassian Jira (v7.12.1#712002)
