Hi Bobby,
Thanks a lot for the heap dump! Our apologies - it does look like you've run
into some sort of bug in the Java Broker. We've really tried to reproduce it
and not been able to - the heap dump at least gives us somewhat a clearer
picture of the nature of the issue.
Do you see this failure in a number of different environments, or are you
always testing on the same (or similar) machines? If so, what are the
characteristics of that machine (memory / number of cores / etc.)
If we still can't reproduce it (and can't deduct what is happening by analysing
the code) we may need to ask you to run some tests for us with patched code
with extra debugging.
Out of interest, have you tried this test with the 0.30 (beta) code? There
have been some changes around the area where this seems to be happening which
might make a difference.

I'll look again at the code in the morning when I may be more awake to see if I
can spot a way your broker got into this state.

> 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
