c-treeACE SQL Server was terminating with an unhandled exception when a non-secure SQL connection attempt failed due to reaching the connection limit. When c-treeACE SQL Server's license allowed logons that are not secure, if a non-secure SQL connection failed because the connection limit was exceeded, the next non-secure SQL connection attempt may have caused c-treeACE SQL Server to terminate with an unhandled exception. The logic has been modified to correct this.
