Bobby Flitter commented on QPID-5786:
-------------------------------------
Rob, thanks for your analysis so far.
I tried jhat - but it crashes. Therefore I used the Eclipse Memory Analyser. It
can also run some of your queries with OQL. But not the ones with the memory
address that you have above.
When I look at the web interface of the qpid server I can see the bindings and
consumers of the queue. Do you have any chance to get the bindings and
consumers of the identified queue from the hprof file ? The exchange binding
has a name. It would help me if I knew the name of the problematic exchange.
Meanwhile I checked all queues via the web interface:
Broker - virtual hosts - default - queues - tmp...
But I see that they all have size 0 while the memory consumption of the qpid
server rises:
Size: 0 msgs (0.00 B)
Pre-fetched: 0 msgs (0.00 B)
Inbound: 0 msg/s (2.58 B/s)
Outbound: 0 msg/s (2.58 B/s)

> Key: QPID-5786
> URL: https://issues.apache.org/jira/browse/QPID-5786
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.26
> Environment: Linux Mint 15 (64 Bit) - any Linux version should do
> Java // OpenJDK Runtime Environment (IcedTea 2.4.4)
> also tested with Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
> Ruby 1.8.7
> Ruby Bunny Gem 1.2.2
> Reporter: Bobby Flitter
> Attachments: amqp_bunny_qpid.pcap
>
>
> When using the hello bunny example program from Ruby together with Apache
> qpid server the memory consumption of qpid seems to grow continuously.
> Steps to reproduce the problem in Linux:
> wget
> http://ftp-stud.hs-esslingen.de/pub/Mirrors/ftp.apache.org/dist/qpid/0.26/qpid-java-broker-0.26.tar.gz
> tar xzvf qpid-java-broker-0.26.tar.gz
> cd qpid-broker-0.26/bin/
> ./qpid-server
> - in a new terminal
> - meanwhile bunny 1.2.2. is available
> - install ruby amqp bunny
> sudo gem install bunny
> - download hello bunny example
> wget http://pastebin.com/raw.php?i=f6MesMCZ -O hello_bunny.rb
> while true; do ruby hello_bunny.rb ; done
> - in another terminal:
> while true; do grep "^VmRSS" /proc/$(pgrep -f qpid)/status ; sleep 1;done
> - memory consumption of java qpid is growing continuously until
> OutOfMemoryError ends the server
> Unhandled Exception java.lang.OutOfMemoryError: Java heap space in Thread
> Thread-1
