Symptom

Within a local logs folder the Archive folder contains many files which can be seen to exceed both the maximum age and the total storage for a single application

Cause

Performance improvements introduced in the Agent kept it from considering the Archive subfolder when checking for pruning by age and size.

Resolution

Update to version 3.6.0 or later of the Loupe Agent.  We recommend at a minimum going to the latest 3.* family agent, available from NuGet.
