Tobias Seppenhauser commented on RF-13250:
------------------------------------------
This bug has also been seen on our customer systems (using RF 4.3.5 and JBoss
7.1). Thanks to Marcel I was able to reproduce this issue with a small bash
script
{code}
#!/bin/bash
echo "Starting the 'long poll of death'! - $(date)"
while true
do
curl
http://localhost/ws/__richfaces_push?X-Atmosphere-Transport=long-polling &>
/dev/null
sleep 0.1
done
{code}
The used JBoss instance had a max heap size of 2GB. After running the script
round about 12hours the server crashed with {{java.lang.OutOfMemoryError: Java
heap space}}
> Extreme memory usage in RF4.3.4.Final and not in RF4.3.3.Final

> Key: RF-13250
> URL: https://issues.jboss.org/browse/RF-13250
> 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
> Reporter: Milo van der Zee

> 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
