Environment - Veritas NBU 5.0 Enterprise Server on Solaris 8 server
                   - Clients are a mixture of Solaris, Windows, and =
Linux running the 4.5MP6 or 5.0 client

Periodically, a client will backup all filesystems for every stream.  =
For example:
  Client A has 3 streams (c:\, d:\, and System_State)
  Stream for C:\ backs up C:\, D:\, and System_State
  Stream for D:\ backs up C:\, D:\, and System_State
  Stream for System_State backs up C:\, D:\, and System_State

This has happened with Windows clients and Solaris clients. =20
All clients that have exhibited this problem were running the 5.0 =
client.
(I haven't seen it on a Linux client, but these are few in my =
environment)
This has happened in both incremental and full schedules.

Earlier backups of the same client, in the same policy, worked as =
expected.
Later backups of the same client, in the same policy, worked as =
expected.

Has anybody seen this? =20
Does anybody have an idea on how to correct this (besides disabling =
multi-streaming)?
