Resolution

The resolution is threefold.

Until the fix in SMS is officially released, a FTF can be obtained trough Novell Technical Services.
The other part is to install CommVault SP9b, then add bCreateParentDir 1 in the OESDataAgent section of the registry.

Cause

During a restore, the initial sequence CommVault Simpana is using to restoring data, is first restore the files after that the parent directory.
Although the SMS smdrd daemon can handle this sequence it caused a severe error which triggered the smdrd to core.

Additional Information

The SMS daemon was adjusted to handle this sequence of restoring better and CommVault adjusted their agent so it can restore data in a more ideal sequence of first restoring the directory, then it's contents.
