Yep, it has been like this forever (since we started using NetWorker),
so it isn't a new-to-NSR6 problem.

I noticed that it was intermittent but that its frequency seemed to be
related to how busy the server was so I:

- have a separate group for our NetWare clients and run it before the
  main group.

- I wound up the "client retries".

- wound back "group parallelism" a bit (once we went to NSR6).

Reduced the pain level quite a bit.

A year or two back someone posted a reasonable-looking explanation of
what causes this but I no longer remember the details.
