IQ Packet send Error

I am using xfire to send soap in IQ starza, the story is like this:

The endpoint “admin” is trying to send a soap to the endpoint “hopeshared”. If “hopeshared” is not online, there is something record in wildfire’'s info log:

2006.06.23 15:48:51 Packet sent to unreachable address

and I donnot know why this occure, can someone tell me ?

But, if hopeshared is online, I listen to each Packet received by hopeshared, and there is none soap packet. and there is nothing in wildfire’'s info log.

If I open the XMPPConnection in debug mode, there is none IQ starta in each case. Why?

when i update my wildfire to 2.6.2, this error disapeared
