Subject [jira] [Closed] (ARIES-1804) Timeout due to connection loss in RSA fastbin provider?
Date Mon, 04 Jun 2018 06:41:00 GMT

     [ https://issues.apache.org/jira/browse/ARIES-1804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Weirig closed ARIES-1804.
------------------------------
    Resolution: Not A Problem

The issue was not caused by RSA but an application issue in regards with Apache LDAP API usage.

Thank you very much for your support.

> Hello,
> I'm running two karaf (4.2.0) servers, one is running the frontend of my application,
the second one is running the backend.
> The backend services are published to 3 clustered zookeeper (3.4.12) servers. In karaf
I have deployed the following RSA features:
> karaf@appsrvtlk()> feature:list | grep rsa
> aries-rsa-core │ 1.12.0 │ │ Started │ aries-rsa-1.12.0 │
> aries-rsa-provider-tcp │ 1.12.0 │ │ Uninstalled │ aries-rsa-1.12.0 │
> aries-rsa-provider-fastbin │ 1.12.0 │ x │ Started │ aries-rsa-1.12.0 │
> aries-rsa-discovery-local │ 1.12.0 │ │ Uninstalled │ aries-rsa-1.12.0 │
> aries-rsa-discovery-config │ 1.12.0 │ │ Uninstalled │ aries-rsa-1.12.0 │
> aries-rsa-discovery-zookeeper │ 1.12.0 │ x │ Started │ aries-rsa-1.12.0 │
> aries-rsa-discovery-zookeeper-server │ 1.12.0 │ │ Uninstalled │ aries-rsa-1.12.0
│
> When I start my karaf servers everything is working fine and my frontend can call my
backend service and gets the result. But after some time (I can't figure out when) it seems
that the connections between the karaf and zookeeper gets lost and I'm getting a timeout when
I call my remote service eventhough all the servers (karaf and zookeepers) are still available
and responding. Exhibitor shows no apparent issues with the zookeepers.
> I have attached the 
>  * relevant parts of my LoginView UI where I declared the @Reference to my service and
where I call the remote service
>  * relevant parts of my AuthenticationService implementation that should be called on
the remote karaf
>  * the stacktrace that I'm getting on the frontend karaf when the timeout occurs
>  * my zoo.cfg file
> From the stacktrace one can see that the LoginView has a non-null fastbin proxy handler
for the authentication service but that after 5 minutes a timeout occurs and there is no line
in the log that shows that the remote service was actually called.
> Many thanks in advance for your support.
> Kind regards,
> Alex
