Hi,

I've written a program which periodically invokes hcitool scan, and
following that propagate out content via obex to the acquired bluetooth
address. I've noticed something remarkably strange occuring throughout the
process. The program which I'd written is invoked immediately after boot.
I'd noticed when I "ps -e" my system, there are a couple of defunct hcid
processes. These defunct hcid jobs are immediately visible right after boot
and the amount of defunct hcid process will to continue grow until the
entire bluetooth service is stuffed. Once the bluetooth srvice is stuffed,
if I were to invoke either hcitool or sdptool...I would get a "connection
timeout" reply. The only way to remedy the situation is to periodically
restart the bluetooth service, once the service is restarted - all of the
defunct hcid process will be cleared.

Btw I'm running Bluez-utils and bluez-libs 3.10.1 on both Fedora 6 and 7
(issue is replicatable on both system). I've multiple dongles, but only 1
dongle dedicated to scanning. Any idea, guys?

Regards,
Ben
