I had posted a thread indicating that the error msg which is the subject of this thread may have been due to Flash issues. I am not so sure any more. I just happened to examine the log of Wowza server and the log is attached below.

I narrowe it down to where it is happening. I am making the following call from the flash client; nc.call(“getUserList”,new Responder(gotUserList,noUserList)); The server handler for the call is : private AMFDataArray userList = new AMFDataArray(); public void getUserList(IClient client, RequestFunction function, AMFDataList params){ sendResult(client,params,userList); } userList was updated with the client name when a viewer client connected before the publisher started to stream content. The publisher before streamign the content asks the server for the list to update its record ---

Issue resolved if anyone is interested… It turns out that one of items in one of the objects in the return value AMFDataArray useList was a null. Once I removed that, there was no EOF error…
