There's a known issue with the 9117-MMC's that can affect system stability. I believe it was ECA337.
I do not believe the kernel has any issues. I've a few AIX 6.1 running some older TL's and they have been rock solid. In fact, looking at your lslpp -l outputs you are using the same TL as myself (6.1 tl7 sp4).

I'd start with looking at your firmware levels of the 9117's, the adapter FW levels as well. Is this lpar part of a HA Cluster? There's a known memory leak that causes a system crash every so many months if your on some versions of HACMP. IBM does offer extended service for AIX 6.1, but there will be no new fixes.

Looking over what has been posted there was a memory exception. Was this running an in house program?

I'm not very good at looking at dumps, and the few times had to rely on IBM/software vendor to address.
I'd start looking at errpt, your firmware, if you are in need of ECA337.

A 9117 isn't a low end frame either, so I'd hope you have IBM support for assistance?

vconsole.conf

VCONSOLE.CONF(5)						   vconsole.conf						  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
	   Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
	   a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
	   Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

	   KEYMAP=de-latin1
	   FONT=latarcyrheb-sun16
