Issue/Introduction

Question: 

If 'above the bar' storage is unavailable, because of a MEMLIMT setting, will the product use virtual storage below 2GB or will the product function or fail?

Answer: 

Insight requires a minimum of 2 Meg above the bar, and a maximum of 64 Meg, if you use the HIST-ACCT-DETAIL option. The collector will fail if this option is used and the storage above the bar is unavailable.
