problem with JxtaServerSocket

Hi all.

I have a freaky problem. On JXTA Peer1 i start a JXTAServerSocket to
receive Data by other Peers. The PipeAdvertisement of the
JXTAServerSocket is published by the method remotePublish() of the
DiscoveryService. My second JXTA Peer starts a Threads every 15
seconds, where these Threads calls the DiscoveryService to find the
remote advertisement of JXTA Peer1 ( getRemoteAdvertisements() ) .
Then they should connect to the JXTAServerSocket with JXTASocket. The
first 6 Threads find the advertisement and connect correctly to the
Peer1. But the 7th Thread only find the advertisement and gets a
ConnectionTimeOut exception while trying to connect to the
JXTAServerSocket of Peer1. What happened??
The following Threads not even find the advertisement....

If I start simultanously JXTA Peer3 with the same function as JXTA
Peer2, same result...

Any help is really appreciated...

Best regards and thanks to all.
