I/O errors in SQL

  • Hello!!

    I have a McAfee ePO setup where we use SQL  for database.

    I noticed few monitors/say tables are not displaying properly in dashboards. .

    When I went through the sql logs I found below errors.

    Could these errors be a reason for not seeing the tables getting populated ?

  • It could be timing out. Contact your McAfee ePO vendor.

    An sich it shouldn't be a cause for the empty dashboards.

     

  • Why do you have McAfee scanning your database files??? Those should be excluded.

  • Absolutely correct.  McAfee could end up damaging your db files, esp. log files.
