After installing hotfix H07 for Spectrum and enabling real time updates for Global Collections, the following issues were found in larger environments with Global Collections that collect many models:

  1. Models may not be added to the global collection

  2. The SpectroSERVER memory may spike up and not return to acceptable levels.


This was due to a timing issue with the internal code. That problem has been corrected in Spectrum version 9.2.3 and above.

This is the release note entry for Spectrum version 9.2.3:

Symptom: Under certain circumstances, the contents of real time Global Collections may not be accurate. In addition, real time Global Collections may cause various performance problems, such as slow model activation and high memory usage.

Resolution: Changes were done in the Real time Global Collections implementation, to resolve accuracy issues and improve performance.
