Flow expired sweeper forming a exponential saw tooth wave pattern(slop) after we upgraded our LTM to 14.1.2.X version. How can I find which Virtual Server/TCP Profile causing this issue ?
You can use AVR module to see traffic reports of each VS and profile.

You can also gather stats of each VS/profile using SNMP.
