The error that we are getting is generally due to huge accumulation of logs in ACS installation folder :

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








Please take a backup of following folder, if auditing is required in our organization :


After taking backup of this folder, please remove logs from following location:


\Logs\Backup and Restore


\Logs\Failed Attempts

\Logs\RADIUS Accounting


\Logs\TACACS+ Accounting

\Logs\TACACS+ Administration

- Stop any anitvirus software that might be running.

- Ensure that if you are using CSMARS, and you are using pnlogagent, then that service is stopped, which can be done from services.msc.

- In the end, Also make sure that Drive on which ACS is installed or intallation folder or sub-folders are not shared.



Please rate if it helps!
