Issue/Introduction

Visualizer Tomcat is failing to start due to high number of locations and visualizerMs.log we see below message:
INFO - 2023-05-25 16:38:54 [c.b.visualizer.sdm.CacheLoader] - Master Data Cache : Number of object to cache for factory: loc is xxxx

Steps:

1. Load or created many locations (ca_location).
2. Create a CI.
3. Now recycle services and we can see the below message in visualizerMs.log 
[c.b.visualizer.sdm.CacheLoader] - Master Data Cache : Number of object to cache for factory: loc is 70112
4. Now launch the Visualizer
5. Search for the CI created in step 2
6. If you now drag & drop this CI to the “main frame” to get it displayed, you will receive an ERROR.

Environment

Release : 17.3

Resolution

The fix is included in 17.4 GA & 17.3 RU23.
