Hi all, We had another site issue of memory blow out today in our operations system.
AMQ had been running for a month and had been stable at 1GB of memory use. Then at 3am approximately it started rising by about 50mb every 5 minutes until we had to restart it 4 hours later to prevent an uncontrolled outage. I managed to get activemq.log, not much information in there, there are a bunch of EOFException and a few of already connected messages for one client. I also got the output of running the query argument to the startup script. I'm not sure how to read this file completely, it's massive, 68MB. What I do see is there are around 33K topics, a large number of those with no subscribers, but I don't think this is necessarily any indication of an issue, my understanding of our system is that the topic number didn't climb rapidly. I noticed on interesting topic which as TotalConsumerCount = 1334, this is way higher than I expected, could this be an indication of any issue? What else can I look for in that output? I thought it would describe everything I would need to understand where the memory is used. Thanks Lionel
