  ****************************************************************
  Incorrect decisions about relocation eligibility may be made in
  a Single System Image (SSI) cluster that includes members
  running on more than one model of machine.  This leads to the
  following message being issued:
    "MSHCPRLE1944I userid: Architecture incompatibility"
  In particular, the main problem is that the virtual architecture
  compare routine does not handle STFLE strings of different
  lengths correctly.  This can lead to a guest being ineligible
  for a relocation when it should be eligible.
  

Problem conclusion

• The virtual architecture compare routine has been corrected.
  

Temporary fix
