Sounds like time to open a service call with IBM.

I searched here:

http://publib.boulder.ibm.com/infoce...v5r3/index.jsp

but couldn't find much on that error code. Just a couple trouble tickets in their database. The solution to those was updating code, but it didn't say exactly what code they had to update. There was nothing for that error code in their message center or Diagnostic Information for Mulitple Bus Systems manual.
