Need help with kernel message from AIX 2.2.1 !!!

[Jason Martin Levitt]

    I keep getting this message from the AIX 2.2.1 kernel:

  Core failure: 255

    No one responded to my posting a couple of weeks ago about
this message. I'm really worried that my machine may fail abruptly
since I seem to be getting the message more frequently now. 
    Can someone at IBM *please* grep through the AIX 2.2.1 kernel
source code and find this string?
