With Cisco Unity Express on a Cisco IOS Gateway, the CUE users cannot access the voice mail, and the callers get dead air when calling to voice mail. This is followed by AIM-CUE module crash and the AIM-CUE logs are out of disk space.
This issue occurs because Advanced Integration Module (AIM)-Cisco Unity Express (CUE) has run out of space. The problem centers around the clean up procedures that run on the module. This process is not running properly, so the module is not cleaning up the database and logs file as expected.
Updating flash with bootloader configuration done.
4) Issue the boot helper command to boot from the installer image, as shown:
ServicesEngine boot-loader> boot helper
5) Once the installer has loaded, type 3, and press enter to begin disk cleanup, as shown:
Welcome to Cisco Systems Service Engine Helper Software Please select from the following 1 Install software 2 Reload module 3 Disk cleanup (Type '?' at any time for help) Choice: 3
6) Press y, followed by the Enter key to begin the process. Do not restart CUE while this process is taking place:
WARNING:: This command will temporarily free up disk space by:
WARNING:: 1) Deleting log files and unnecessary system files. WARNING:: 2) Compacting the Voicemail database. WARNING::
Do you wish to run this command now (y,n)? y
Note: Disk cleanup can take up to 30 minutes. Do not reboot or restart the CUE while this occurs, or everything may be lost.
7) Type 2 and press Enter to reboot, as shown:
Welcome to Cisco Systems Service Engine Helper Software Please select from the following 1 Install software 2 Reload module 3 Disk cleanup (Type '?' at any time for help) Choice: 2
The system should now boot normally. Once CUE is up, check the output of the show sysdb command. The 'usedPercent' value should fall to the 40-50 range.
Even though the system is fully operational now, the same issue could occur later. For a permanent solution, upgrade the CUE version to 2.1.2 which can be downloaded from Software Download-Cisco Unity Express 2.1.2.
For information on the upgrade process, refer to these documents:
Note 1: The preventive action is to periodically reboot the AIM-CUE module by issuing the service-module service-engine 0/0 reset command . It is not necessary to reload the entire router. The module runs the expected clean up procedures after the reboot.
