If Version 10.5 of the App Visibility portal and App Visibility collector are running in a high availability (HA) environment, pg_xlog files are not deleted automatically from the installationDirectory\ADOP_DB\pgsql\data\pg_xlog folder and fill up the disk space on the hard drive. Eventually, this overloads the App Visibility portal and App Visibility collector and the server fails.
This issue is fixed in Fix Pack 10.5.00.001. See 10.5.00.001: Fix Pack 1 for more details.
Add the following command to the end of the file:
Save the postgresql.conf file.
Restart the App Visibility portal and collector services.
If the App Visibility portal or collector cannot be restarted, restart the App Visibility PostgreSQL service and then start the portal and collector.
