Marcel Šebek commented on RF-13250:
-----------------------------------
Hello.
I can see the same behavior with RF 4.3.5 after upgrading from 4.3.3. Some
client still runs the old version of atmosphere and generates a lot of requests
of the form
/__richfaces_push?__richfacesPushAsync=1&pushSessionId=650b92c8-db1c-4e97-81e2-80cf684bbe68&X-Atmosphere-tracking-id=de550cf9-c1eb-4f26-9bd3-ae94187e4711&X-Atmosphere-Framework=1.0.10&X-Atmosphere-Transport=long-polling&X-Cache-Date=0&_=1392213448240
Each such request leads to "Committed error code 400" in server log. I also see
a big number of AtomicBoolean classes in heap dump. Currently I cannot say that
the number of the instances increase only when these old-version requests are
comming, but it looks so.

> 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
