NIF DB2 Navigation error

Hello,

I have been trying to investigate the following error that I am getting when running an agent against a db2 type database but am at a loss:

Database collection error: E:\Program Files\IBM\Lotus\Domino\data\crm\dev\CRM135DEV.nsf: NIF DB2 Navigation error.

Does anyone know what the error is.

Many thanks

Fiona
