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.To resolve this issue, clean the disk first. This defect applies to CUE versions 2.0.1 and 2.1.1. For a permanent solution, upgrade the CUE version to 2.1.2
