I don't know about Big Brother monitoring, but can't you modify the threshold a bit?

hmm, I can.
But still client would like to know, what processes are consuming/holding so much memory, if we need to change threshold.

As I've already said, big part (25%) is held by system for page cache. Also kernel takes quite a big chunk (29%). To check applications' memory consumption you can use prstat -s rss

Got it. But ideally, so big percentage should NOT be hold by page cache as well as kernel.
Without reboot, can it be released to normal stats ?

I've seen way higher page cache percentages Smilie And the server didn't mind. System doesn't want to waste unused resources. So those stats ARE normal. Maybe except for the kernel size, but for now I can't access any Solaris 9 system for comparison.

Your stats are normal. Unused memory is wasted memory. If your Big Brother report settings confuse free memory (cache) and used memory, that's the piece to fix.

I understood. Thanks Jilliagre and bartus11 for your comments.
I will change threshold value in BB.
