原因：

Kernel version < 2.6.9-55.0.2.EL This can be caused by a Red Hat kernel bug that appears to have been corrected in:kernel-2.6.9-55.0.2.EL Reference:http://rhn.redhat.com/errata/RHSA-2006-0132.html Bugzilla 173981 - kernel bug at mm/prio_tree.c 

解決方案：

-- To implement the solution, please execute the following steps:1. Obtain and install the RPM for kernel-2.6.9-55.0.2.EL (or newer). ---額外注意：kernel-2.6.9-55.0.2.EL是rhe4.5，也就是說小於4.5會有此bug2. Re-attempt the failed upgrade process by using the DBUA or manual (CATUPGRD.SQL).
