Disk subsystem usage optimization ("Lower the load on the disk I/O") for the Database update task in Kaspersky Anti-Virus 8.0 for Windows Servers Enterprise Edition Service Pack 2 (version allows the application to allocate some amount of RAM (to be specified in the product settings) for storing downloaded files. This decreases the load of the disk subsystem and the operating system on the whole. By default, the option is disabled.

The "Lower the load on the disk I/O" option has the following limitations:

  • The amount of RAM allocated to the task must be at least 400 MB (512 MB is the default). The limitation is due to the size of the antivirus databases; if the limit is less than 400 MB, the update task will be completed with a file operation error.
  • The amount of RAM allocated to the task cannot exceed the amount of available RAM; otherwise, the task may fail to start. The system log will reflect the error as Internal application error occurred. Error code: 0x800705AA. Subsystem code: 0x1 (Windows). In such case, decrease the amount of allocated RAM in the task properties.
