Please describe problem better (how many times, what devices, does it work 
better/worse on other platforms) or send a minimal program to sample this
(one written specifically to show this bug, not the application you are
developing minus everything you don't want us to see). I on the other
hand can tell you, that the programs I have written can stay open for hours
with connections going and coming.

Conformed

Created test application. 
(see SVN http://bluecove.googlecode.com/svn/bluecove-examples/bluecove-tester/)
http://bluecove.sourceforge.net/bluecove-tester/

I see the problems when running server application on Windows XP, BlueCove 1.2.2
and client on Noka 6265i or another WinXP with BlueCove.
Java 1.5, MS USB Bluetooth dongle.

Tested number of connections opened to server is 150. Running Time hours...
There are small percentage of not established connections but after retry client
connects successfully and data transmitted without errors.
Test Server Accept only one connection a time.
StreamConnectionNotifier is not closed. acceptAndOpen called after connection is
finished.

After 3 hours of discovery and connections. USB Bluetooth dongle no longer
discoverable and server not working. MS Mouse connected to the same dongle not 
working.
Need to unplug the dongle and connect it again.

Just recently run my test application again.
Server BlueCove on XP with MS USB Dongle was working for 5 hours accepted 1700
incoming connections.
Client app running "Client Stress Start" on Noka 6265i no errors or dropped
connections until the battery died.

Another update on the problem. 

Running BlueCove v2.0.0 with Microsoft Bluetooth stack, D-Link DBT-120 USB

more than 3,000 Connections made and running....

If you have a problem like one describe in bug report try using different USB 
adapter.

Hi,
I'm getting this same problem using Suse 11.2, bluecove 2.1.0, Trendnet 
Bluetooth Adapter TBW-105UB or Dlink Bluetooth Adapter DBT-122.
Any idea?
Regards.
