High memory usage and sweeper aggressive mode activated
Hi all, my active F5 (5000) is currently consuming 83% memory usage, which is just climbing into the Red!

I have also noted a large number of the following messages appearing in the ltm log file.

I run LTM/ASM/APM on the F5's and quite a few iRules.
Can someone please share some advice on how I can reduce the memory consumption?
Many thanks,
Anthony
