APAR status
Closed as program error.
Error description
When faceting against a search index with many index fields (for example, over 10000 dynamic columns), faceting queries can cause abnormally high CPU usage. Eventually this can cause the CPU to max out when there are multiple shoppers browsing concurrently.
