Steve Loughran commented on HADOOP-18091:
-----------------------------------------

First fix is to disable auditing by default, HADOOP-18094

Big fix is to stop using ThreadLocal. I have a plan there

> {{ActiveAuditManagerS3A}} uses thread locals to map to active audit spans, which (because they are wrapped) include back reference to the audit manager instance and the config it was created with.
> these *do not* get cleaned up when the FS instance is closed.
> if you have a long lived process creating and destroying many FS instances, then memory gets used up. l
