Openfire MultiUser Chat - Scalability

Question

I created a sample program that joins a multi user chat room in Openfire Server.

I changed the "Maximum Room Occupants" of multi user chat room to "unlimited".

On joining around 850 user in a multi user chat room, I am getting the following exception

org.jivesoftware.openfire.session.LocalSession - Internal server error
java.lang.NullPointerException
at org.jivesoftware.openfire.nio.NIOConnection.deliver(NIOConnection.java:356)
at org.jivesoftware.openfire.session.LocalClientSession.deliver(LocalClientSession.java:857)
at org.jivesoftware.openfire.session.LocalSession.process(LocalSession.java:289)

at org.jivesoftware.openfire.muc.spi.LocalMUCRoom.broadcast(LocalMUCRoom.java:1155)....

CPU Usage is also increasing to 100% at this time.

Please advice me to solve this problem.

According to me you should go for high configured server.That have good RAM and Processor. So, it handled more users in multi-chat.

Just talk once in openfire community with moderators.Take advice from them. They will give you best solution. here you can go.

Thank You hope this will help you.
