opening and closing connection with port happening fastly
- by michale
We have a Main application named "Trevor" installed in 2008R2 machine named "TEAMER12" which is slow now. One more application named "TVS" also running in  and found there were many connections per second occurring to port 5009.
netstat tool mentions that some fast connection open/close seen for port 5009
So first it will be listening mode like shown below
TCP    0.0.0.0:5009           TEAMER12:0        LISTENING
then establishes connection like 
TCP    127.0.0.1:5009         TEAMER12:49519    ESTABLISHED
TCP    127.0.0.1:5009         TEAMER12:60903    ESTABLISHED
After that iwill become TIME_WAIT and i could see several entries like shown below
TCP    127.0.0.1:49156        TEAMER12:5009     TIME_WAIT
after that it will establish connection like
TCP    127.0.0.1:60903        TEAMER12:5009     ESTABLISHED
TCP    127.0.0.1:64181        TEAMER12:microsoft-ds  ESTABLISHED
again it will go several entries like TIME_WAIT
TCP    127.0.0.1:49156        TEAMER12:5009     TIME_WAIT
Finally it will establish  like this
TCP    172.26.127.40:139      TEAMER12:0        LISTENING
  TCP    172.26.127.42:139      TEAMER12:0        LISTENING
TCP    172.26.127.42:5009     TEAMER12:64445    ESTABLISHED
TCP    172.26.127.42:64445    TEAMER12:5009     ESTABLISHED 
Can any body tell me whats the reason behind why many connections per second occurring to
port 5009 and why application slow?
