Cisco ACS 5.2 "active sessions are over limit"

Hello,

I keep getting this message on Cisco ACS 5.2:-

Cisco  Secure ACS - Alarm Notification
Severity:  Warning

Alarm Namedelete 20000 sessions
Cause/Triggeractive sessions are over  limit
Alarm  Detailssession is over  250000
Generated OnWed May 02 14:41:28 SAST 2012

I have not noticed any adverse impact on performance of the Cisco ACS as a result of this but I'd like to know how to resolve this before it causes problems.

Thanks

Re: Cisco ACS 5.2 "active sessions are over limit"

Q. What is the "delete 20000 sessions" alarm I see on my ACS 5.x dashboard?
A. This alert is informational and is generated because the ACS View keeps track of authentication sessions.

The ACS View maintains all the sessions (RADIUS/TACACS Authentication/Authorization/Accounting). It can keep only 250,000 sessions at a time. Whenever it crosses 250k, it will try to delete 20k sessions, and will send an alarm (the one that you see on the ACS Dashboard).
