Details

Avaya Aura Communication Manager Messaging (CMM): Release 5.2.1.
Midsize Business Template (MBT): Release 5.2.1.

Problem Clarification

When calling into the voicemail, users hear the CMM greeting, but the call is dropped before they finish recording the message.

When the issue happened in the past, a backup restore was performed by the BP in order to recover the voicemail.

CMM has an active alarm: VM AUDIX_FS 1. This alarm indicates that used space on / "root" partition has been exceeded: more than 80%

Maintenance log shows another event:

Cause

As per PSN003522u, this is a known issue for CMM 5.2.1 on MBT (Midsize Business Template). and it can result on Messaging system degradation, as it is filling up root partition.

If the root space is more than 80% full then system will generate VM AUDIX_FS Warning. There will be a LOW_FREESP message in maintenance logs. There will be Messaging performance degradation as your root space becomes full.

Solution

As mentioned on the PSN, DEV is working on a fix. There is no ETA on the fix at this time.
