I have posted a message few month ago , and got reply suggesting to
upgrade the WinPcap version to
3.1 ( I have used the beta version of 3.1).
I have installed it few days ago and still have the same problem  ( copy
from the last post) :

I am writing a network sniffer that uses WinPCap  3.1 Beta on Win
2000\2003 servers.

This application works fine under any server I have used till now,
but recently I have installed it on blade server (  IBM blade centre
8677-3xa and OPM Switch IBM optical pass thru Module  ) , and crossed
strange behavior :

When my application starts it is capturing packets for a period of time
, then packets stops for any reason.
When using other application that uses WinPCap ( Packetyzer ) I get the
same result ( even when their buffer is not full).

When I use Ethereal in regular mode( not displaying packets in real time
) also the packets stops after few seconds , only when I check the
option of  " Update list of packets in real time" packets are being
captured all the time.
( I have got the answer that it does nothing but in the UI but still it
has effect !!! ).

I have also written a small application based exactly on the WinPCap
docs , and it is also acting the same ( stopped getting packets after
few thousands of packets ).
