Some searches are using a great deal of memory. Why is that?
Adding a notable index or summary indexes to the default indexes to be searched causes correlation searches to re-detect another finding based on the content of a previous correlation search firing.
The solution is to remove the notable index (or summary index) from the list of indexes to be searched by default.
See "Configure multiple indexes" in the Splunk App for PCI Compliance Installation and Configuration Manual for more information.
