Here is the problem I'm faced with.
Our ZAM as been running fine for 12 month without a glitch, but for the last
month we have being having problem with our Network Discovery. We perform a
discovery every weekend and our last successful scan was on March 23 2008.
Since then every time the scheduled discovery with the default discovery
options is run, if it finds more than 3 unassigned IP in a row, the job
stops but is reported as Completed. No data is collected or at least it is
not updating the SQL database. I have try to run the scan on the subnet
manually, same result.

Our ZAM version is 7.50.0024 IR11 last PRU is 2008-04-02
Any ideas of what could be causing this kind of behaviour?
