I am looking for jabber server that can support thousands of concurent users. From jabber.org’'s comparison chart, I knew that Jive Messenger was tested on 5000. When I tryed to reproduce tests, following exception was thrown:
Exception in thread “Socket Listener at port 5222” java.lang.OutOfMemoryError: unable to create new native thread
at java.lang.Thread.start0(Native Method)
at java.lang.Thread.start(Unknown Source)
at org.jivesoftware.messenger.spi.ConnectionManagerImpl.addSocket(ConnectionManage rImpl.java:242)
at org.jivesoftware.messenger.net.SocketAcceptThread.run(SocketAcceptThread.java:1 31)
My machine:
Intel Pentium 4 3Ghz with 2Gb RAM
Windows 2003 Server
WM options:
-server
-Xmx1536m
Jive Messenger 2.2.2
With this settings only 136 users can connect to the server.
It is much smaller than announced on jabber.org. Could you describe how this tests where performed or publish real number of concurent users that server can support.
