Error description

When a "Security Configuration Report" is generated via the
Admin Console, java.lang.OutOfMemoryError errors maybe seen in
the Deployment Manager Servant region or Base Application Server
Servant region.

The .phd file will show the following leak suspect, which is a
large HashMap of held by the
com/ibm/ws/sm/workspace/impl/WorkSpaceImpl object:

To confirm this is the problem please reproduce the issue with
the following trace:
com.ibm.ws.sm.workspace.impl.WorkSpaceManagerImpl=all=enabled

The following trace point will show how createWorkSpace getting
called:
.
 Trace: 2009/01/08 12:02:52.602 01 t=8CBE00 c=UNK key=P8

   ThreadId: 00000044
   FunctionName:
com.ibm.ws.sm.workspace.impl.WorkSpaceManagerImpl
   SourceId: com.ibm.ws.sm.workspace.impl.WorkSpaceManagerImpl
   Category: FINEST
   ExtendedMessage: Call stack info of createWorkSpace(prop):

orkSpaceManagerImpl.java:380)

com.ibm.ws.sm.workspace.impl.WorkSpaceManagerImpl.createWorkSpac
e(WorkSpaceManagerImpl.java:102)
............. and so on

By looking at the stack trace from the above trace point we
observed createWorkSpace being called from the following
security code:
ListManagementScopes.java
ListKeyStores.java
ListPersonalCertificates.java
ListSignerCertificates.java

As well as seeing the above createWorkSpace calls, the
WAS_HOME/profiles/default/wstemp/ directory will contain many
directories named anonymous* such as below:

anonymous1233674535300
anonymous1233674535519
anonymous1233674535740
... etc
