Re: Solaris 11 memory usage

[Martin Pala]

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
