    Hello Managers,
    We have some strange errors related to CPU and memory,
    I ran memory exerciser (memx) and it came out with no
    failures.
    My system is Alpha 500/333 workstation with DU 4.0b,
    working as a netscape server for all clients.

    Following are the /var/adm/messages or dxconsole
    messages which will be keep repeating

    ffffff0006ac04bf corrected ECC error in B-cache during
    D-cache fill.
