[MX] MS-MIC and MS-MPC syslog message: pconn_server_send_ipc: failed to send message

  [KB32732] Show Article Properties


Summary:

When Cntrl+c is used to abort any of the show services output or show commands, the "pconn_server_send_ipc: failed to send message" message may be logged. This article explains why this failure message is logged and suggests a simple solution.

 

Symptoms:

The log shows that the pconn connection is broken:

------
May 24 22:33:45 gw 3. kb-dc_re 0:% DAEMON-3: (FPC Slot 0, PIC Slot 2) ms 02 mspmand [188]: pconn_server_send_ipc: failed to send message - type 23, subtype 182
May 24 22:33:45 gw 3. Kb - dc - - 0:% DAEMON - 6: (FPC Slot 0, PIC Slot 2) ms 02 mspmand [188]: msvcs_session_flow_sweep: callback failed (error = 3)
------

 

Cause:

This is expected behavior if any of the show services output or show commands are aborted with Cntrl+c. When Cntrl+c is used, a command is aborted immediately and the pconn session ipc pipe broken. Therefore, when the message that the Command Line Interface (CLI) is failing is sent, it fails with a "failed to send message" syslog message.

 

Solution:

When Cntrl+c is used in the MS-MIC or MS-MPC service cards in your MX device, this behavior is expected. There is no service impact.

If required, these messages can be filtered by using the steps described in KB9382: [Junos Platform] Example - How to prevent certain syslog messages from being written to the log file
