Core issue
This problem is due to the presence of Cisco bug ID CSCeg81851.
On the CiscoSecure ACS for Windows, when the usage quota is enabled for the default group, the RADIUS service is restarted in random intervals from 20 seconds to 5 minutes. This issue is seen in the CiscoSecure ACS versions 3.2.1(20) and 3.3.2(2).
The RDS.log shows something similar to this:
RDS 23/11/2004 01:12:47 E 0028 1972 Exception trapped at D:\ccData\snapViews\Snap_rgoren_matis-build12@ismg_israel_acs@ACS-B-708_3-3-
2_B-6\ismg_israel_acs\Acs\DZRadius\RADIUS.C:386 [Exception occurred processing authentication packet]
RDS 23/11/2004 01:12:47 E 0028 1972 Exception trapped at D:\ccData\snapViews\Snap_rgoren_matis-build12@ismg_israel_acs@ACS-B-708_3-3-2_B-6\ismg_israel_acs\Acs\DZRadius\RSERV.C:1363 [Exception trapped in worker thread]
Resolution
As a workaround, perform either of these steps:
- Do not configure the quota.
- Download and upgrade the CiscoSecure ACS for Windows software to version to 3.3.3.
