Description (partial)

Signature updates can take an excessively long time and sensorApp may fail if the IPS has extensive signature customization.
The time to install the update is affected by the size of the customized signature definition.  The more changes that have been made to the signature definitions (sig0), the more likely the issue is to occur.
