Shared objects might have stopped working when you upgraded your flash player to a version which defaults to AMF3, and you didnts explicitly set it to AMF0.
Occasionally I see issues using amf3 and shared objects. And notice I wrote 'might'. It may be legitamate bug.
However consider that if you are not requireing your clients to use higher versions of flash, they may connect with a defaulting AMF0 and others are in AMF3 which will often cause a problem.
Do you have any errors in your log regarding the RTMP failing to decode some data?

I can reproduce the issue with a single call to getSharedObject(room, "roomslist",true); placed in roomStart
I've done a red5 application with just that line of code and the connection from the flash client fails consistently (and curiously) from the third connection attempt on!

Way back when, (0.7) there was a bug with persisting custom objects to SharedObjects. When I persisted a SharedObject with a custom externalizable value in it, sometimes it would corrupt the SharedObject and the only solution was to delete the SharedObject by hand. I don't know if this was fixed, but maybe it has something to do with what you're experiencing.

Just a small update regarding my issue, today I made a boolean search trough the repository for the exact revision number (between rc1 and rc2) where my Shared Objects's stopped working!
I have compiled and tested about 10 Red5 revisions between Rc1 and Rc2 and I have identified revision r3431 as the revision in which my shared objects stopped working properly!
The SVN logs shows what was changed in this revision:
=========================================
Fix http://jira.red5.org/browse/APPSERVER-311 with patch provided, and re-enable system regression test for it
Modified /java/server/trunk/test/fixtures/red5-selftest.swf
Modified /java/server/trunk/src/org/red5/io/amf/Input.java
=========================================
Also I have changed the log level for org.red5.io to DEBUG and you can see below what I get now in the logs when the error triggers.
My issue is not completely solved yet but now I am closer to the exact issue. Hope this helps someone!

Are you storing custom objects in your SharedObjects?
2009/3/20 Naicu Octavian <naicuoctavian at gmail.com>
With RC1 everything works fine.
With Rc2 and the svn version, my flash chat application connects just fine to my red5 server side chat application, some persistent sos are created server side in Application.roomStart , everything works almost super smooth.
During this phase I get some WARN's tough:
2009-03-20 16:45:50,093 [pool-4-thread-16] WARN org.red5.server.Context - Bean lookup failed for r0users..soservice in the application context
whenever the execution reaches a getSharedObject or createSharedObject for r0users
Now if I disconnect and connect again with the flash client app, the connection wont go trough. The executions stops when it hits a getSharedObject or createSharedObject inside Application.roomStart.
The exact stack trace is :
