RE: SYSLOG: TCP/IP crashes when sending many messages

Dennis,
 
I am sorry, Information was not correct .
The log says  this(I put nnn to hide customer's IP):

 Message ID . . . . . . :   TCP2615       Severity . . . . . . . :   20       
 Message type . . . . . :   Diagnostic                                        
 Date sent  . . . . . . :   04/02/10      Time sent  . . . . . . :   16:24:37 
                                                                              
 Message . . . . :   TCP/IP gateway nnn.nnn.nnn.254 unreachable.                 
 Cause . . . . . :   TCP/IP gateway nnn.nnn.nnn.254  is no longer reachable from  
   this system. Connections routed through gateway nnn.nnn.nnn.254  may fail if no
   other route to the connection destinations can be found.                   
 Recovery  . . . :   If the problem persists then contact your network        
   administrator. If gateway nnn.nnn.nnn.254  becomes available again another     
   message will be posted to indicate the gateway is now reachable.         
 
This seems to be overload in network as you can see from this article:

Thanks and best regards,

(Your STRTCPIFC / ENDTCPIFC sequence is incorrect.)  Is there a job log on
the server (remote) system?  What is the OS release level of the remote?
How are these files being sent?  FTP?  Something else?  What services
actually end?  What is the status of the line before ENDTCPIFC?  What type
of line is this?
