The abend occurs in the MirrorRandomRead routine of mm.nlm.  Upon further investigation it is discovered that they still have a NetWare 6.0 partition on this NW 6.5 server which has not been upgraded.  Using Portlocks imaging software may also create this situation.  Executing "Mirror status" from the console will report a single element mirror object which is stored in the hotfix area of the partition. 

Execute the server console command "mm upgrade partitions" and reboot the server to correct the problem.
