Hi,
the attached error message ("cpu system usage ...") is for CPU test ... not
related to memory usage. High "cpu system" usage may be for example sign of
heavy disk I/O activity and/or swapping (memory shortage) - check vmstat output
for details.
If the memory usage report is problem, please can you provide output of "echo
::memstat | mdb -k" and "monit status" (just the System service part is
sufficient).
Regards,
Martin
