The "RSS" (Resident Set Size) column is simply how much virtual memory is currently in physical RAM.
The “S” column is the process state and has the following codes:
PROCESS STATE CODES
D uninterruptible sleep (usually IO)
R runnable (on run queue)

Please send the file that is generated from “tar logs tech-support” to Aruba Technical support if you see any process in a state of “z” or “t” under the “S” column.
