Communication Crashes with a C++ Runtime Error When Downloading Database to XPP


When downloading the database to the XPP (CT-30 locks), the Communication Server crashes. The following error message appears:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program C:\Program Files\OnGuard\Lnlcomsrvr.exe
This application has requested the Runtime to terminate in an unusual way.  Please contact the application's support team for more information

The Windows Application Event Viewer shows the following error properties:
Faulting application lnlcomsrvr.exe, faulting module version 6.3.249 msvcr90.dll version 9.0.21022.8 fault address 0x0005bb47
These errors appear on any workstation that the XPP is connected to. The database download fails whether the Communication Server is running as an application or as a service.


This error indicates that there is a problem with the XPP. The XPP must be repaired or replaced.

Additional Information

Two support tickets have been logged with the same errors, both resolved by replacing the XPP.
