Hi All,
I have a new cisco 3750 stack comprised of 8 members (6 x 3750G-48PS and 2 x 3750V2-48PS) running 'c3750-ipservicesk9-mz.122-58.SE2.bin'. I am seeing high memory utilisation, it seems to sit fairly stable and I do not see an increase but this has only been running a few days. No errors or performance issues. Should this be a cause for concern?
Attached a show processor memory output.
Any advice welcome...

Wow. 8 switches in a stack. That's not "best practices". I would start breaking a stack into two if there is ever 6 and more switches in a stack.

Thanks. I am considering this although Cisco docs state up to 9 switches in a single stack. Is there any documentation around keeping this to 6?

The 3750 can stack up to 9 switches. There were cases in my experience that stacking 6 and more can cause some heart-stopping issues. The most common issue I encountered is when I would issue an "interface range" command that spanned multiple switch chassis and then I get lag that gives you the impression that the stack (or parts of the stack) has crashed.
