Juraj Húska commented on RF-13250:
----------------------------------
I have reproduced the issue with the description provided by community.
The reproducer can be found at
[this|https://github.com/richfaces/richfaces/tree/RF-13250] branch. Test script
will start an Arquillian test, which will start JBoss AS 7.1.1.Final instance
with 256Mb max heap size. It will then try to simulate 4 users (not
simultaneous), receiving push events. Another script is in the meantime making
invalid push requests causing the heap exceeding its allowed size.
Steps to reproduce:
# checkout referenced branch
# issue:
{code}
cd examples/push-demo/
mvn clean verify -Dtest.timeout=2160000
{code}
# from another terminal window issue:
{code}
cd examples/push-demo/
bash malformedPushRequestScript.sh
{code}
# where {{-Dtest.timeout}} is timeout for running the test in milliseconds,
e.g. 2160000 == 6 hours, I was able to reproduce it in 4 hours
# after e.g. 4 hours check that the test output contains {{OOM exception}}
This OOM exceptions which can be found in the server log:

> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 4.3.4, 4.3.5
> Environment: Gentoo Linux, Tomcat 7.0.39, MyFaces 2.1.12, Tomahawk
> 1.1.14, RichFaces 4.3.4, APR 1.4.5

> Hello,
> I did an upgrade from RF 4.3.3.Final to 4.3.4.Final and the application
> started to crash with 'Out Off Memory' errors. I changed the POM back to
> 4.3.3.Final and the problem is gone.
> I also started seeing this message lot's of times:
> {{WARN org.atmosphere.cpr.AtmosphereResponse - Committed error code 400}}
> I don't know if that has anything to do with the error. I set
> {{org.atmosphere.cpr.sessionSupport}} to {{true}} and I did not see the
> message again. But still the application went out-of-memory.
> In the crashed system heap dump I see a lot of:
> - AtomicBoolean (751.000, 15.0MB)
> - ConcurrentLinkedQueue
> - AtmospereRequest$Builder (60.042, 13.8MB)
> To me it looks like it has something to do with Atmosphere. Any ideas?
> Thanks,
> Milo van der Zee
