<p class=MsoNormal>Hey Guys,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We have the following problem:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Bbwin is sending traffic to 2 monitoring servers and is
encrypted via stunnel. If one of the monitoring servers goes down, the number
of ports being used by bbwin client increases to the point where the box is
unusable – no more ports available on the windows box being monitored. If
we kill the bbwin process, the problem goes away temporarily – after a
short period of time, the problem returns. The problem continues even after the
failed hobbit server recovers, and only clears up when we kill the bbwin
process.<o:p></o:p></p>

<p class=MsoNormal>Can something be added to my stunnel.conf to prevent this
from happening? Any help would be greatly appreciated. Thanks.<o:p></o:p></p>
