    The SMSYSPROCESS table is a /SDEMagic SYSTEM table which is used to monitor loaded instances of metadata.
    For each loaded metadata instance, a new record is created in this table.  The records in this table are critical for the proper function of the Magic Application.  Some uses include:
    1. Identifying a metadata instance by its Server Name and ProcessID.
    2. Verifying that an instance of Metadata is healthy, by tracking its latest CHECKPOINT value.
    3. Preventing multiple instances of metadata from loading in the same process.
    4. Tracking Magic license usage (KO and TKO columns).
    5. Verify that there are no active instances of metadata prior to running the DBAdmin Tool.
    The entries in this table are integrally related to records in the NAMSYSSERVERS table.
