An I/O (Input/Output) error caused the termination of a connection with an interface client. This is relevant only to GGSN (Gateway GPRS Support Node), and only applies to M, MX and T series routers.

The SERVICED_CLIENT_ERROR message is logged each time an interface client connection is terminated.

When a SERVICED_CLIENT_ERROR event occurs, a message similar to the following is reported:

The cause is due to an internal error, such as in the following:

  • Page fault
  • Internal table full
  • Process core dumped

Examine the following output to help determine the cause of this message:

Look for any related events that occurred at or just before the SERVICED_CLIENT_ERROR message. For example, there may have been a page fault or an internal table is full.

Perform these steps:

  1. During a maintenance window, as it will impact transit traffic, try restarting the serviced process. For more information on restarting a process, refer to Restart a Junos Software Process.
  2. If the failure messages continue, open a case with your technical support representative to investigate the issue further.
