I have a problem with ActiveMQ Artemis version 2.10.0 which is running on a docker. That's exactly a threading problem (logs below). At some point in the logs, I see this entry:
...ANSWER
Answered 2020-Jul-13 at 14:27This issue, as far as I can tell doesn't really have anything to do with threading. The issue is, as the error message indicates, that the "TimedBuffer is expired on path 0" or in other words "TimedBuffer@51b01960 is not responsive." The "TimedBuffer" is the component which is responsible for flushing data to disk, and it's taking too long to flush data so the broker's "critical analyzer" shuts the broker down and emits a thread dump for debugging purposes.
The "critical analyzer" is a service within the broker which monitors important tasks and if those tasks take too long to complete then the critical analyzer will take action. The default broker.xml
contains this configuration for the critical analyzer:
QUESTION
I am running our corda application in a docker environment. Due to this I generate node info files for each node and copy them to the nodes to bring up the application. Initially I assumed I could use the same node info file as long as the node.conf remained the same, however this is not the case.
If I use the same node info files after a rebuild. The nodes come up fine connecting with each other. However when a flow is initiated, I get the following AMQP error from one of the nodes (security.ActiveMQJAASSecurityManager.validateUser - Couldn't validate user {}), complete stack trace is below.
If I copy the node info file and the contents of the certificates directories used when the node info file was generated I get contract validation error.
Note that each time I am starting up the corda network from scratch.
- Is this behavior expected?
- If the node.conf remains the same then to what attributes are the node info files tied into of a given build (root certificate etc)?
- Is the root dev certificate changed each time it builds?
I am trying to understand how this is setup in order to setup our test environment.
Thanks

...ANSWER
Answered 2018-Aug-23 at 00:52According to the corda certificates docs, the nodes require certificates because they use them to connect to each other (it is a permissioned network after all). As a result you cannot use the same certificates and therefore each node must have its own certificates.
If you want to automate your build process, I recommend using the network bootstrapper tool to bootstrap your network. You can use the same config file (i.e. the same settings as you are using docker), you just have to have several copies of it: e.g. node1.conf, node2.conf etc. Once you have all the files in a repository, you can simply run
QUESTION
I'm trying to connect through tls1.2 a client and a server. The client doesn't accept negotiating the cipher suite and don't know how to handle it.
I activate the ssl debug log, using the jvm arg javax.net.debug=SSL,handshake and was possible to see that the server receives the ClientHello. The server does the following:
...ANSWER
Answered 2018-Feb-06 at 11:25I found the problem. The server wasn't reading the handshake timeout property and using the default, the result was rejecting the connection. I changed the server code (opensource project) and the timeout was fixed.
QUESTION
I am trying to connect a simple paho client to artemis wildfly broker. I am getting this when I try to connect my client:
WARN [org.apache.activemq.artemis.core.protocol.mqtt] (Thread-2 (activemq-netty-threads-164875171)) Error processing Control Packet, Disconnecting ClientAMQ119032: User: null does not have permission='CREATE_DURABLE_QUEUE' on address $sys.mqtt.queue.qos2.JavaSample.
I added an application user to wildfly, I gave him 'guest' as role, and in my standalone-full.xml, I found this:
...ANSWER
Answered 2017-Sep-01 at 18:35I believe this is a known bug in the version of Artemis embedded in Wildfly.
I recommend you try using ActiveMQ Artemis standalone rather than embedded in Wildfly. The version in Wildfly is based on 1.5.x which has some bugs (specifically in relation to MQTT). Standalone Artemis should be more stable.
