A. By design, the SMS uses all available memory so a high memory usage is normal. This happens as the SMS pre-allocates (caches) memory for often used data and binaries (TOS and SMS database) so it is common to see memory utilization above 90%.
You can view the SMS memory utilization from the SMS console or the SMS CLI.
From the SMS Console;
On the SMS console got to the System Health by selecting Admin -> General -> System Health and viewing the System Health Statistics section and looking at the memory line item or the memory graph.
From the CLI:
On the CLI issue the get health CLI command and look at highlighted areas;
The above example displays that the SMS is running with a CPU utilization of 40% with a memory utilization of 95% and 2GB of RAM.
