Operating system call connect failed (error no. 79) Urgent!


In my solman 4.x. sm21 logs, I see the error soo many "Operating System call connect failed ( error no. 79)..


More Logs from sm21


Documentation for system log message Q0 I :

The specified operating system call was returned with an error.

For communication calls (receive, send, etc) often the cause of errors

are network problems.

It could also be a configuration problem at operating system level.

(file cannot be opened, no space in the file system etc.).

Additional specifications for error number 79

Name for errno number ECONNREFUSED

Interprocess communication (e.g. TCP/IP) connection refused by partner.

This usually means that the necessary receiver program is not running.


Anybody has any idea why I am getting this? How can I test the error, or fix it?


I will post the points for sure!!
