Error description

  • DB2 may crash when trying to replay
    federated XA log records produced on earlier fixpacks
    
    The stack seen will be:
      memcpy
      sqlqgRFwdFedPrep
      sqlpRecDbRedo
      ...
    
    Situations where this could arise would include explicit
    rollforward after a restore or when performing a rolling upgrade
    of an HADR pair.
    
    When upgrading to a new fixpak or when rolling fixpak back,
    please, avoid using federated XA log records produced on a
    different fixpak.
    If this is unavoidable, please, request Special Build from DB2
    Support to replay old logs.
    After the issue is resolved, please, un-install Special Build
    and take a new backup to avoid any need to replay problematic
    log records again.
