Is there a release date on this?
I am using 5.2.2.0 on a W2K node (server is 5.2.2.5 on AIX 5.2-03).  Tried to 
do an Image backup and we got a few error messages during the backup.  A quick 
search at ibm.com returned a single entry that matched my error almost to the 
letter, and indicated the problem has been fixed in the software version 5.2.4, 
but I don't see that version on the FTP site yet.  It also indicated that a 
work around was to set resourceutilization to 1, and that seems to work, for 
now.
