There are some doubts about if SDM is impacted or has restrictions or has constraints when Antivirus is processing the server where SDM is installed and running.
Do scanning w when SDM is not being used with high intensity or running Discovery or BF.
SDM by purpose is a demand software, so, usually not intensive use usually has been detected before.
Also running BFs in D2D mode, impact is low.
In D2F BF, where processing is large enough and the files are stored on the same server, please here consider, do scanning antivirus process outside BF running hours.
From your Antivirus product specifications, you would check how your antivirus impact Java memory or Tomcat applications.
