Default.trc inundated with Security DEBUG entries

My development portal is creating an incredible number of default.trc files per day. When I open them, it appears that most of them are DEBUG/PATH entries. I have gone into Visual Admin and set the logging level to Error and restarted the system. I even made sure that the Error logging level propagted down the tree, yet the entries still appear.

Looking at the entries in the default.trc it appears that the entries have to do with security/authentication (com.sap.engine.services.secuirty.sessionmanagement). Is there somewhere else that DEBUGGING is turned on? Thanks in advance.
