Josh,
Unfortunately I didn't copy the Audit event files. But this issue happened twice with me on 04/20 and 04/26.
Around 39595 Audit Events generated on CMS Node 1 which I used to run the Report. Around 85 files with file size 96 KB are generated.
We have 365 audit data in the system.
SAP is working on our Audit thread utilization 100% issue which is also happening without landscape report but I am able to reproduce the 100% utilization issue with landscape report. Incident number 113791/2016
