[AVM] Even we have problem of newly created IMM object is taking some
time to be available on other nodes
it will be a implementation problem and it is not related
to IMM specification .

[AVM] Again, this is also not related to IMM specification , if we
resolve above this issue will not rise .
Gary, Is this issue you are facing in case where you are creating
object
on one node and admin operation performed on different node ?
or on same same node ?
