I have an issue with a Panorama VM indicating high memory usage.
Using the following resources:
top - 10:59:58 up 82 days, 1:07, 1 user, load average: 4.22, 3.89, 3.87
Tasks: 156 total, 1 running, 152 sleeping, 0 stopped, 3 zombie
Cpu(s): 39.2%us, 1.8%sy, 0.0%ni, 58.0%id, 0.9%wa, 0.0%hi, 0.1%si, 0.0%st
Mem: 16447708k total, 16354760k used, 92948k free, 13208k buffers
Swap: 2097084k total, 2091588k used, 5496k free, 8151152k cached
This has only recently occurred, hasn't always been the case in terms of memory usage.

This is probably not the best explanation, but there are a lot of articles on the topic, for example:
