ASF Echo-Thread Server: Network connection is broken

Troubleshooting


Problem

This article describes one of the possible reasons for error messages ASF Echo-Thread Server: asfcode = -25582: oserr = 0: errstr = : Network connection is broken. Error writing to network shown in the instance message log file.

Symptom

When you investigate the content of a logical log file with the onlog utility you may observe error messages like

ASF Echo-Thread Server: asfcode = -25582: oserr = 0: errstr = : Network connection is broken.
Error writing to network

or

ASF Echo-Thread Server: asfcode = -25580: oserr = 32: errstr = : System error occurred in network function. System error = 32.


Error writing to network

in the Informix instance message log file.

Cause

This can happen if you pipe the onlog output to a viewing utility like less, more, pg, etc., for example:

onlog -n 1234 | less

If you exit the utility (by Interrupt Ctrl-C or typing 'q' in the case of less, etc) before the onlog has read through the full logical log file, the onlog utility abruptly ends the communication between itself and the Informix server. This causes the before mentioned error messages will be written to the Informix instance message log file.

Diagnosing The Problem

If you observe the error messages every time an onlog output is interrupted only, then this description applies.

Resolving The Problem

In this situation these messages can safely be ignored.
