A few thousand 1MB to 4MB messages will run you into the heap limit in a hurry, even with your 8GB of heap. (I assume that's an 8GB JVM on a host with more than 8GB RAM, not a smaller JVM on an 8GB host.) Do you really need to dump gigs of messages on the broker when this happens? (A few thousan

Thanks again for the quick replies gentlemen. I actually got everything up and running again - this time by restarting both the activeMQ service as well as the apache/tomcat service. Yesterday I did the same but it did not work. Yesterday I actually had to delete the DB and log files from the DB

>From the sound of it, no one queue is overloading the broker; rather, you have lots of queues that each have some messages, and the aggregate load is the problem. So don't look for the problem child, and instead focus on protecting the entire broker. First, you should enable Producer Flow Contro

Hi, Are there any queues where there is no movement vs. ones where there is a steady shift in enqueued/dequeued counts? Or any topic where there are one or more consumers and any pending messages to be dequeued? I wouldn't typically expect a memory limit on a queue to cause a consumer to not be

Do you have any (and I mean ANY) messages that aren't consumed for long periods of time, including any messages sitting in the DLQ? As Jim referenced, even a single old message can keep all data files alive, running you up against the storeUsage limit. Tim On Apr 14, 2016 7:16 AM, "James A. Robin

Thanks for the reply Jim. We do have the webconsole enabled and I am looking at the queues page. These are all fairly active queues - I.E there are currently about 20 queues with between 20-80 messages in them. The problem is and what I've read is that the messages are no longer dequeing. My l

I've recently been left (with no working knowledge) an activeMQ windows server installation. The problem I'm having (which I've read as much as I can about) is that the memory percent used keeps climbing and eventually I'll have to restart the activeMQ service and delete the db.data files and a

You might see if you can get debugging output similar to what KahaDB offers: http://activemq.apache.org/why-do-kahadb-log-files-remain-after-cleanup.html I had a similar situation and the KahaDB debugging showed that the problem was due to un-acked persistent messages sprinkled throughout the old

Hi, It's been quite some time now and I just wanted to follow up for archiving purposes. Since we updated everything to 5.13, we don't see the issue any more. I am convinced it had been caused by the 5.7 client library. Best regards, Martin On Sat, Jan 9, 2016 at 6:24 AM, Tim Bain wrote: > Grea
