The issue can be reproduced at will with the following steps:
1. The audit log files shows /var/tmp/oradiag_iam/diag and /opt/app/oracle/middleware/local/config/instances/ohs1 and are labeled as s a WEB SERVER httpd.worker
2. Filling up the /var filesystem, which causes the "audit backlog exceeded" messages and eventually the system to hang
