Hi all
I am still trying to get to the bottom of this one, and I am determined to fix it. For Solaris, at least. :-)
First off, for the developers out there - how is the Percentage and Used figures determined? The numbers I am getting do not appear in the client data anywhere. Also, what figure does the server use for the Total?
Looking at my own issue, I have the following.
Memory Used Total Percentage [image: red] Physical 4294963143M 8192M 4294967246% [image: green] Swap 3506M 16383M 21%
I suspect the problem might be something to do with the reported free memory, and the reported physical memory. The output below comes from my client data.
[prtconf] System Configuration: Sun Microsystems sun4v Memory size: 8192 Megabytes System Peripherals (Software Nodes):
[memory] 0 0 0 16804936 12641392 36 247 0 101 101 0 0 5 1 0 1 886 3158 688 0 0 99 [swap] total: 3590152k bytes allocated + 0k reserved = 3590152k used, 13187064k available
My thinking is that having 12641392k of free memory on a system with only 8192M (8388608K) leads to a division by very small or negative number, resulting in daftness. (This appears to only happen inside zones, where odd things abound with regards memory and CPUs.)
This theory appears valid so far, because from time to time (when memory usage is high) the free memory drops to below 8192M and I get sane figures - although probably still wrong.
If I am correct, I will probably need to hack the client script a little to more accurately reflect the total memory and the free memory. I will figure out how to do that once somebody can confirm which numbers the server uses to determine the Used and Percentage figures.

Hi all
Another contract, another emial address. :-) Hope you all had a good festive season.
Quick question. Was there ever a resolution to this issue? http://www.hswn.dk/hobbiton/2009/03/msg00036.html Searched the archive, and couldn't find one.
To recap, this was where memory reports something bizzare, like this
Memory Used Total Percentage red Physical 4294961768M 8192M 4294967229%
green Swap 1600M 8191M 19%
