Re: Consumers hanging on a queue although there are messages in it

I dont know if this is exactly what is happening with you but the code below shows that if the broker memory is full, the broker will be unable to page in messages (and dispatch them). https://www.paste.org/98451 If this is your case this issue somewhat mitigated by https://issues.apache.org/jira

Re: Artemis Core bridge and clustering question

If you have properly configured your cluster then core bridges are automatically created between the nodes behind-the-scenes. If you have 2 independent clusters and you want to connect them together then you would need to manually configure core bridges. For configuring core connections see the do

Re: Consumers hanging on a queue although there are messages in it

Hi... Did you guys see some log lines like the following? WARN Queue - queue://STORE, subscriptions=1, memory=0%, size=200, pending=0 cursor blocked, no space available to page in messages; usage: Usage(Main:memory:queue://STORE:memory) percentUsage=0%, usage=0, limit=1

Those two (profiler capture, or thread dump) should also be smaller and you might be able to attach them directly. If not, just use one of the free file-posting sites if you don't want to use your own Dropbox or Google Drive or similar. Tim On Thu, May 2, 2019, 7:28 AM Tim Bain wrote: > A CPU s

Re: ActiveMQ cannot handle too many topic with redeliveryPlugin

A CPU sampling capture from a profiler such as JVisualVM will be far more effective than a thread dump, if it's an option. A heap dump will probably not be useful here, since it doesn't sound like you're running out of memory. Tim On Thu, May 2, 2019, 4:39 AM Christopher Shannon < christopher.l.

Re: Apache configuration issues

What version of ActiveMQ are you using? That line is written when a consumer closes with unconsumed messages. Is that occurring here? Your description of the consumer code sounds like you're creating a consumer per message consumed (an anti-pattern), in which case 1) unconsumed messages when closi

Re: ActiveMQ cannot handle too many topic with redeliveryPlugin

20k messages and 30k topics is quite a bit so I'm not surprised the CPU usage is very high. The reason the CPU is high after stopping the publishing is probably because you have a backlog on the broker that the consumers need to work off. You might also have a lot of messages being processed for

No problem, I can provide heap dump but the file size is over 1GB. Please provide location /link to upload, thanks. -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
