We have a Highly available setup of Portal for ArcGIS 10.6.1 with one Primary and one Standby server each. The OS is Wiondows Server 2016. We are running into Disk space issues on the standby server due to numerous DB folders being created automatically under the portal installation path C:\arcgisportal. Sometimes every 2-3 minutes, a new db folder is created. This issue is appearing only on the standby server. Is this behavior normal for the product?
