Issue
When upgrading Sigma, improperly handled Longtext messages can cause the Sigma server to shut down unexpectedly.

Cause
During the upgrade process, new Longtext messages were added correctly. However, existing messages from the previous version were copied over without being properly upgraded. This mismatch in message formatting or structure leads to instability, causing the Sigma server to stop periodically.
Resolution
To prevent this issue during an upgrade from a version earlier than 4.05:
- Verify the Longtext folder exists in the Sigma Data directory.
- Run the Sigma upgrade program to ensure all Longtext messages—both new and existing—are correctly upgraded.
⚠️ Important: Do not manually copy old Longtext messages into the upgraded system without proper conversion.
