[omniORB] Problem with Persistent POA

[srinath duraisamy]

@Duncan Thanks for replying.

My scenario is like when a server get crashed and restarted by watchdog.
For persisitent POA it should bind to the same port(using -ORBendPoint
2810).

After Server get crashed I used the netsat -nop TCP to find the port info.
The particular port is in FIN_WAIT_2 state.
Since server is getting crashed it will not be in a position to send the
final FIN. The opearting system should take care of cleaning the ports. In
my case Windows is not cleaning up that port.
When I searched for this problem I found out for the apache servers they are
configuring a time delay for flushing out this ports.

My question is there anything can be anything done on the ORB level for
cleaning up the ports like reducing the time delay, without depending on the
operating systems to clean up the ports while server getting crashed.

Thanks in advance.
