Fixes are available

APAR status

Closed as program error.

VMM supports rangeRetrieval, but VMM only queries the initial
set of attribute values from LDAP i.e 0-1000.

Which goes infinitely and CPU usage reaches 100%.

****************************************************************
* PROBLEM DESCRIPTION: Virtual member manager (VMM) runs       *
*                      into an infinite loop when configured   *
*                      to retrieve ranged attributes.          *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
LDAP supports range retrieval, eg. Active Directory.
VMM also supports range retrieval; But was querying for
initial attribute values eg.0-500 Or 0-1000. hence was
resulting in infinite loop and yield CPU usage to 100%.
This resulted in performance issues.

Problem conclusion

VMM will itereate over all the attribute values in LDAP and
get them properly from LDAP.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.43, 7.0.0.23 and 8.0.0.3.  Please refer to the
