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

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.

3. Reproduction
========================================================================= =
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.

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.
../../../../../../../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
