Deploying to ssisdb (sql server c2 audit enabled) fails

Hi, 

SQL 14.0.3035.2 with C2 Audit enabled. When deploying new SSIS packages to SSISDB the server shuts down, due to being unable to write to trace log. 

If I disable C2, the deploy works fine (tough not direct from VS, see https://social.msdn.microsoft.com/Forums/sqlserver/en-US/2c063b57-8571-41e7-8a95-3ce4a105a5e3/unable-to-deploy-ssis-after-vs-2017-update-1580?forum=sqlintegrationservices).

Is it a bug or am I missing some permission somewhere?
