According to the result from Session logs viewer - SS&C Blue Prism, a potential issue caused by retaining large volumes of session log data is that database performance is degraded. Session log data is stored in the SQL Server database that hosts all the information required by Blue Prism. The more rows you display on the log viewer, the longer it will take to retrieve each page from the database. Depending on the size of your log and the performance of your databaseserver, this could take some time. Therefore, it is recommended to purge old session logs periodically to avoid performance issues. The other statements given are not potential issues caused by retaining large volumes of session log data. References: Session logs viewer - SS&C Blue Prism
