Hi,

We are in touble with our TCP/IP gateway machine.

The problem is the following :

 Sometimes ( generally during the week-end ...) this machine
seems to hang TCP/IP traffic without any logical reason. 

 1 -  it cannot accept any TCP/IP connection. 

 2 -  The 2 disks are still visibles and we can access to them
      using DOMAIN_OS with a "cd //dsp3" command.

 3 -  Listing the processes on this machine gives the folling :

----------------------

[surf:23143] ps -ax //dsp3
  PID TTY     STAT  TIME COMMAND
    1 ?       S <   0:59 [ init ]
    2 ?       R   36165:10 null
    3 ?       S    26:28 purifier
    4 ?       S     0:47 purifier
    5 ?       S    52:16 unwired_dxm
    6 ?       S     0:00 pinger
    7 ?       S   117:31 netreceive
    8 ?       S   755:26 netpaging
    9 ?       S    11:38 wired_dxm
   10 ?       S   1755:25 netrequest
   21 ?       S    31:08 netpaging
   22 ?       S    30:58 netpaging
   25 ?       S    39:23 netrequest
   27 ?       S    39:21 netrequest
24664 ?       S     3:28 [ named ]
24668 ?       S    10:35 [ rwhod ]

-----------------------

  4 -  There is no spm so we cannot crp to it, the only processes which
       seems to run are init,named,rwhod.

  5 -  This machine is connected to a HP835 which is our external gateway to 
       the internet. 

  6 -  The ethernet controller ( 802.3 ) seems OK.

This machine is a DN3500 with 16 Mb of memory and two 700 Mb disks,it is running
DOMAIN_OS 10.2 with BSD4.3 and AEGIS, normally the following processes are 
running on it :

  - tcpd
  - sendmail
  - named
  - rwhod
  - writed
  - spm

I precise that this machine is also a big file server for all our students so 
it is not easy to stop it at any time ... I know it is not very smart to do 
this but we have no choice at this time.

- Is it a known bug ?

- Does the 10.3 solve this trouble ?

- WHAT CAN I DO ???
