ACS errors.

Unanswered Question
Jun 21st, 2007

Today I had the following problem with my ACS server:

Event Type: Warning

Event Source: Perflib

Event Category: None

Event ID: 1016

Date: 6/21/2007

Time: 12:10:38 PM

User: N/A

Computer: CiscoACS

Description:

The data buffer created for the "CSTacacs" service in the "C:\WINNT\system32\tac_mon.dll" library is not aligned on an 8-byte boundary. This may cause problems for applications that are trying to read the performance data buffer. Contact the manufacturer of this library or service to have this problem corrected or to get a newer version of this library.

Data:

0000: 14 38 16 00 0c 04 00 00 .8......

which was then follwed by this error:

Event Type: Error

Event Source: Perflib

Event Category: None

Event ID: 1008

Date: 6/21/2007

Time: 12:14:38 PM

User: N/A

Computer: CiscoACS

Description:

The Open Procedure for service "CSTacacs" in DLL "C:\WINNT\system32\tac_mon.dll" failed. Performance data for this service will not be available. Status code returned is data DWORD 0.

Data:

0000: 02 00 00 00 ....

This eventually led to the ACS services crashing and attempting to restart. I had to reboot the box in order to restore the services.

Any ideas as to the cause of this problem? The server has been up and stable for 4 years and is just now starting to give problems.

BTW - running ACS 3.3 on Windows 2000 Server w/ SP4.

Hi,

The error messages that you have reported, is associated to a bug, but is marked as cosmetic,

CSCdu43103 : ACS Perflib cosmetic error message 8-byte boundary alignment

I would suggest you to do following,

Please remove all the file from following location and then try ( these files are debug files, so we donot require them) :

\CSAuth\Logs

\CSRadius\Logs

\CSTacacs\Logs

\CSLog\Logs

\CSMon\Logs

\CSAdmin\Logs

\CSDbsync\Logs

- Also, if you have ran CSSupport.exe that is under, \Utils

Re-run it and if TACACS or RADIUS packet dump was on, turn it off.

- In the end I would suggest you to go to ACS version 3.3.4.12 with Patch 2

Regards,

Prem
