1. Problem
========================================================================= =
NTFimcnd crashed while 200k objects was created and the deleted in IMM, the
classes associated with these objects were also removed. 2. Analysis
========================================================================= = A
huge number of objects, about 200k objects, were created in IMM with PBE
disabled. Then these objects were deleted in one CCB (by deleting the root
object). After deleting the objects, the classes were also removed. Then the
crash happened. Oct 19 19:45:04 SC-2-1 osafimmnd[22799]: NO Number of objects

../../../../../../../opensaf/osaf/services/saf/ntfsv/ntfimcnd/ntfimcn_imm.c:167:
get_rdn_attr_name: Assertion '0' failed. When NTFimcnd created notifications,
some information had to be looked up in IMM. NTFimcnd only asked for class
information in case of object creation: static SaAisErrorT
saImmOiCcbObjectCreateCallback(SaImmOiHandleT immOiHandle,
SaImmOiCcbIdT ccbId,
const SaImmClassNameT className,
const SaNameT *parentName, const SaImmAttrValuesT_2 **attr) { …
dn_ptr = get_created_dn(className, parentName, attr); … } static void
saImmOiCcbApplyCallback(SaImmOiHandleT immOiHandle, SaImmOiCcbIdT ccbId) {
… switch
(ccbUtilOperationData->operationType) { case CCBUTIL_CREATE:
rdn_attr_name = get_rdn_attr_name(
ccbUtilOperationData- >param.create.className);
internal_rc = ntfimcn_send_object_create_notification(
ccbUtilOperationData, rdn_attr_name,
ccbLast); … } In this case, NTF was still
handling notifications for a big number of created objects. Usually, NTFimcnd
cached the class information. But because these objects belong to many
classes, it had to ask IMM for class information. But the class was already
removed in IMM. IMM was much faster to create and delete the objects and class
(with PBE disabled), while NTF was still processing the objects, so the
information was not there in IMM anymore, and the crashed happened. Oct 19

========================================================================= = Can
be reproduced like below: - Disable PBE 1. Create a huge amount of objects with
one parent object. 2. In my case, I created 2 root objects of two different
classes with about 100k child objects each Delete first root object, then
delete the class associated with this object. 3. Delete second root object,
delete the class associated with this object.
