  AST-driven IP Server Process Problem? 
 The Question is:
 
I have written tcp/ip server using system routines (sys$qio etc) in FORTRAN.
Server can accept 16 simultaneous connections.
All I/O(s) is done at AST level.
My clients in Window2000 and request some data
from server every 5 seconds. Data length is about 400 bytes.
 
After 2 or 3 hours laters, VAX side sockets look like as follows
UCX&gt; sh dev bg585/full
 Device_socket: bg585                        LOCAL               REMOTE
                              Port:           5500                 1051

                              Service:
 
                                                           RECEIVE       SEND
                                   Queued I/O                    0             0

  Options:  REUSEADR
  State:    ISCONNECTED PRIV
  RCV Buff: WAIT
  SND Buff: None
 
When "Socket buffer bytes" begins to increase,
no data send to a client. Even a observed the
network with a network analyzor, no packets coming from server but client is
 able to continue sending. Eventually server side gets in SUSPENDED mode.
Please note that I have enough "small buffers" and "large buffers" free.
 
What else parameter I should set and from where?
Thanks in advance.
Please urgent !
 
 
 The Answer is :
 
  Please contact the Compaq Customer Support Center, as the details of
  the TCP/IP Services version and ECO level installed on the system as
  well as details of the application source code will be required here.
