Christofer Dutz commented on FLEX-34648:
----------------------------------------

I did encounter a similar problem in a scenario where a server was producing an insane amount
of messages (Actually the server was firing CRUD events for each Creation/Update/Delete of
an entity on a server. While it was no problem during testing in a first produktion-like run,
all went fine. But as soon as someone actually logged in to the client, the heap was almost
instantly flooded. We too noticed that even the ttl of a message wasn't actually respected
and messages were not cleaned up. Unfortunately the side-effect was that the list in the browser
was not useable cause the list updated its content about 1000 times per minute, driving users
nuts. So we gave up the push and reverted back to simple pull and manual refresh. As the problem
was no longer pressing and BlazeDS was not yet Apache, I didn't continue working on this :-(
... but now I'll think of a way to simulate clients.

> a memory leak occurred when sending alot of AsyncMessage through BLAZEDS in a real time
systems which is heavilly using messaging however we are increasing the jvm heap size  to
4 GB 80% of the size is occupied by AsyncMessage objects this is very clear from the generated
heap dump.
