I´m not sure I understand your question.

What´s your operating system?

"Unix" is a generic term for a family of operating system (http://en.wikipedia.org/wiki/Unix). SAP runs on quite a few of them

Ok - here we go.

Buffers (table, CUA etc.) are put into shared memory pools. Depending on which OS you use, they can´t exceed a certain size and must be taken out of the pool - and be created separately. Basically there´s no problem with that but you may need to increase your OS parameters to allow additional segments.

You can have a look at the actual segments using

ipcs -m

To see which pools were created during system start use

sappfpar pf=<instance-profile> check
