GBLSECNOTGDS, Global section xxxx is not a GT.M global section
Run Time Error: This indicates that when attempting to startup a database file, GT.M encountered an existing global section whose contents it did not recognize.
Action: Investigate whether you have a global section name conflict between GT.M and some other application. GT.M uses GT$ as a prefix for all global section names that it creates. Make sure no other application in the system is using the same naming convention; it is very likely the global section contents are damaged. If necessary, report the entire incident context to your GT.M support channel.
