Problem
Due to an issue with the IBM Informix database management system, the sblob_dbspace may get full
during the replication process and cause the Cisco Unified MeetingPlace Application Server to fail. The
failure will see the Application Server reboot multiple times when attempting to start MeetingPlace
services, and the services will fail to start when attempting to use the CLI command mpx_sys restart.
Additionally, output from the CLI command mp_replication status on either node 1 or node 2 may
show that the connected (remote) server has a very large value in the Queue column.

Workaround/Solution
Cisco has made a hotfix available called sblob_dbspace-fix.sh. The hotfix creates a second database
chunk (sblob_dbspace2), which is approximately 1GB in size or 20x larger than sblob_dbspace. Once
applied, the system will automatically start filling sblob_dbspace2 once sblob_dbspace is full.
