TCP 10058: Can't send after socket shutdown

[Anth105]

Hi Gurus

Env :  Master NBU 6.54  running on AIX 5.3
          Media NBU 6.54 running on AIX 5.3
          Client  5.1 MP3  running on Win2k sp4

Description
I am getting  a  file read error (13) on a consistent basis regardless of the  backup ( Full or incr).  The servers are  behind a DMZ  but I have set the BPCD connect-back to use the VNETD port and it worked for a long time but now all I receive are 13 errors on one specific server.   Seaching through the  logs files ( bpbkar and bpbrm), I noticed the backups seems to fail after 1 hour when the TCP socket is closed.

Client bpbkar.

Any help would be much appreciated

Is the firewall for the DMZ forcibly shutting down the VNETD connection between this Windows 2000 client and your AIX media server after 1 hour?  The logs in your firewall might indicate whether this is happening.

Hi

try increasing the client read timeout on the media server. Also run netstat on the client for port 13724 . Large number of connections in TIME_WAIT state indicates a problem.
