Resource Conservation Activity
The resource conservation activity graph shows the number of times the appliance entered Resource

Conservation Mode (RCM). For example, if the graph shows
n
times, it means that the appliance has
entered RCM
n
times and exited at least
n-1
times.
Your appliance should enter RCM infrequently and only during a very large or unusual increase in mail
volume. If the Resource Conservation Activity graph shows that your appliance is entering RCS

Note about Memory Page Swapping
The system is designed to swap memory regularly, so some memory swapping is expected and is not an
indication of problems with your appliance. Unless the system consistently swaps memory in high
volumes, memory swapping is normal and expected behavior, especially on C170 and C190 appliances.
To improve performance, you may need to add appliances to your network or tune your configuration to
ensure maximum throughput.

at the same time that excessive memory swapping takes place. This might be an indication that you have
a capacity problem. You may want to save this page as PDF to preserve a snapshot of system
performance for later reference (or to share with support staff). For information about generating PDFs
