According to my sources, this was fixed in the latest 2.3.1 ptf and the 5.0
Looks like you are at at 2.3.0. You should call Support and get the

yes, we saw a similiar problem after migration from NV 4.1 with
MLM-Products to NV 5.
The performance went down dramiticly on our AIX-Nodes. After
stopping the MLM-
Products (MLM,SLM and SIA) and deleting them the problems has
The monitoring of our AIX-nodes we are doing now with TME10 DM
3.5 without any
What now we cannot use are the private MIB-variables. We can
