We use: Netbackup 5.1 MP4 client on netware 6.5 SP4 on cluster (two nodes).
When we make backup off nss volumes with OFM (Open File Manager) off
veritas they load a snapshot of the volume.

But after the backup, the snapshot was not release. In the time, the access
of ressource began very slow.We then migrate de volume, and the snapshot
was released.

Any idea?

We apply the latest patches.
