Error description
When fullyMaterializeLobData is set to false in the JDBC driver custom properties for the DB2 driver being used, the session persistence code fails to write LOB's to the session table. The data is instead stored in memory and thus can be lost when the server is recycled.
Local fix
Keep fullyMaterializeLobData set to true in the driver custom properties settings.
