In some environments, AMSP could cause high disk input/output when the common scan cache was on. This is a known issue in Deep Security 10.0.

By default, the AMSP common scan cache is enabled. To disable it, do the following:

  2. Go to the Deep Security Manager root folder.
  3. Run the command below:

    dsm_c -action changesetting -name settings.configuration.disableAmspCommonScanCache -value true
