[JDEV] some questions about xdb and transport

[Gang Liu]

Hi,

	I use RedHat 6.1 and Jabber server 1.4.1 from cvs.
	I am doing some study in xdb backend and my own transport.I have changed xdb config in jabber.xml.
  <xdb id="xdblinker">
     <host>vista.internal</host>
     <ns>jabber:iq:auth</ns>
     <accept>
        <ip/>
        <port>5280</port>
        <secret>secret</secret>
     </accept>
  </xdb>
   The xdblinker is a program in another host.It can handle "jabber:iq:auth" correctlly. I also add a transport to jabberd.The transport reveives message packets from user A, reply the packet and forward to another user B.

	I found jabberd always huangup servel seconds when user b is offline.I have used tcpdump to view the network traffic.
I found that jabberd sent nothing to xdblinker.Xdblinker received those packets together after severl seconds,but the xdb_get() already timed out.
