Hi John,
you should be able to find this data in the following file:
.metadata.plugins\com.softwareag.is.core\logicalServer.properties
Might be that this file is not writable by the user used to run Designer.
I do not think that this happens during Stop/Start of IS, more likely this happens during restart of Designer.
Regards,
Holger
