When the AutoDiscovery completes, it creates the AdiscResultSet model which shows the history of the discovery. The problem is that the attribute can only hold 4MB worth of data. If you discover thousands of devices, or hundreds of large devices (lots of interfaces) the data stored is larger than 4MB which would cause the SpectroSERVER to crash.
There are couple of ways to resolve this:
1. Break up your discovery so that you are not discovering as much in one discovery.
If you are discovering 10000 devices in 1 discovery break it up into 4 so you are only discovering 2500 per discovery.
2. Install 10.3 with the 2nd BMP (Spectrum_10.03.00.BMP_10.3.002) and install Spectrum_10.03.00.D19 on top.
In Spectrum_10.03.00.D19 the code was changed so that not only will the SS not crash, but Spectrum does not store interfaces that do not have a mac address associated. Interface information is not available in the History anyway, so there was no need to save it.
3. Upgrade to Spectrum 10.3.1 when it becomes available (first quarter FY 19) where the code changes from both Spectrum_10.03.00.BMP_10.3.002 and Spectrum_10.03.00.D19 are included.
Even though the interfaces with no mac address are not stored, when the modeling portion runs, it will still model those interfaces.
