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?

pspp-dump-sav

pspp-dump-sav(1)						    PSPP Manual 						  pspp-dump-sav(1)

NAME

       pspp-dump-sav - dissect SPSS system file

SYNOPSIS

       pspp-dump-sav [-d | --data[=maxcases]] file...
       pspp-dump-sav --help | -h
       pspp-dump-sav --version | -v

DESCRIPTION

       The  pspp-dump-sav program reads each SPSS system file file and prints its contents.  The output format is useful for debugging system file
       readers and writers and for discovering how to interpret unknown or poorly understood records.  End users may find the  output  useful  for
       providing the PSPP developers information about system files that PSPP does not accurately read.

OPTIONS

       -d[maxcases]
       --data[=maxcases]
	      By  default, pspp-dump-sav does not print any of the data in a system file, only the file headers.  Specify this option to print the
	      data as well.  If maxcases is specified, then it limits the number of cases printed.

       -h
       --help Prints a usage message on stdout and exits.

       -v
       --version
	      Prints version information on stdout and exits.

BUGS

       Some errors that prevent files from being interpreted successfully cause pspp-dump-sav to exit without reading any additional  files  given
       on the command line.
