A corrupt association in the SpectroSERVER database
Resolution
As a work around, move the the $SPECROOT/SS/Modules/libvhmvmware.dll file out of the $SPECROOT/SS/Modules to a temporary directory and then restart the SpectroSERVER. This will prevent the SpectroSERVER from crashing.
Open a case with Spectrum support to have the core/mdmp file analyzed further to identify the models associated with the corrupt association and resolve.
When resolved, move the the $SPECROOT/SS/Modules/libvhmvmware.dll file back into the $SPECROOT/SS/Modules directory and then restart the SpectroSERVER.
