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?

cr_open

cr_open(3)						     Library Functions Manual							cr_open(3)

NAME

       cr_open() - open crash dump for reading

SYNOPSIS

DESCRIPTION

       The library call opens a crash dump and passes back a crash dump descriptor.

       The path argument points to a path name naming a crash dump directory or file, and must not exceed bytes in length.

       The CRASH * to which crash_cb points is set to a crash dump descriptor, which can then be passed to the other functions to access the crash
       dump.

       flags is a bitmask of zero or more of the following flag values, which affect the operation of future calls to libcrash routines  for  this
       crash dump, except for cr_verify(3), which has its own flags parameter.

       The library will not attempt to verify checksums of files in the crash
			     dump if this flag is set.

       The library will write messages to stderr during time-consuming operations
			     (decompressions and checksums) if this flag is set.

RETURN VALUE

       Returns zero for success.  Other possible return values are described in libcrash(5).

EXAMPLES

       The following call to opens crash dump contained in the directory and returns the crash dump descriptor For an example of reading the crash
       dump see the cr_read(3) manual entry.
