Issue
Longtext messages not correctly upgraded can cause the Sigma server to stop.
Environment
RAM
Remote Alarm Manager
Longtext
Server shuts down
Cause
Upgrading of the Longtext messages was not carried out correctly.
Resolution
All new Longtext messages were added correctly, but messages that existed before the upgrade were copied in and not upgraded.
The result of this was that the Sigma server would periodically stop.
When upgrading Sigma from a release earlier than 4.05, ensure that the Longtext folder is present in the Data folder, then run the Sigma upgrade programme.
