Zen running on NW 6.5 sp7.
Version =

We are currently pushing out a large number of Office installs and the
server has locked up each night. No abend messages, nothing in the logs,
I'm thinking it's time to patch Zen probably because of a memory leak.

Where to start? I'm downloading ZEN7_with_SP1_R2.
However, near the bottom of the download page, it states that there are no
updates included for desktop management in this service pack.

Does anyone know what patches I need ?
