    hey netkey

    can you download the system log files and sent them to support ?

    I suspect this may be a memory issue;

    to test memory you will need to reboot the server

    To run the memtest, restart your server and right after the POST, hit 'Esc'
    and you'll get options to run the test.**It's best to let the memtest run
    until it's completed.

    Default

    Also run the Repair Filesystem utility from the Extended tools after checking the mem.
    All the best,
