Symptoms

WLS_Portal managed server becomes unresponsive after being up for several hours.  A 'kill -9' needs to be executed on the WLS_Portal process and then the WLS_Portal can be started again.  The WLS_Portal.log is filling up quickly with debug messages like the following:

<Debug> <SecurityRoleMap> <cpp-devtest-app.army.mil> <WLS_PORTAL> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)' for workmanager: null@null@weblogic.kernel.Default> <<WLS Kernel>> <> <> <1335293299453> <BEA-000000> <XACML RoleMapper: accessing role OracleSystemRole: DENIED>
<Debug> <SecurityRoleMap> <cpp-devtest-app.army.mil> <WLS_PORTAL> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)' for workmanager: null@null@weblogic.kernel.Default> <<WLS Kernel>> <> <> <1335293299454> <BEA-000000> <XACML RoleMapper: accessing role Operator: DENIED>
<Debug> <SecurityRoleMap> <cpp-devtest-app.army.mil> <WLS_PORTAL> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)' for workmanager: null@null@weblogic.kernel.Default> <<WLS Kernel>> <> <> <1335293299454> <BEA-000000> <XACML RoleMapper: accessing role CrossDomainConnector: DENIED>

These then seem to lead into:
