APAR status
Closed as program error.
Error description
MongoDB can spike to 100% CPU utilization when a query spans a very large data set, such as the job log entries. These spikes in CPU utilization can be seen during busy job operations and when the server is in an idle state. When the MongoDB service is consuming 100% CPU utilization, the IBM Spectrum Protect Plus Portal may become unavailable. User's will not be able to log into the portal until CPU utilization drops. Affected levels: IBM Spectrum Protect Plus 10.1.10 and later

Problem conclusion
A hint is now provided that guides MongoDB to use the efficient index. By using the efficient index, MongoDB no longer inefficiently scans and sorts the large amount of data in the job log MongoDB collection, which dramatically reduces the required CPU cycles to complete the query. This ensures that MongoDB does not use 100% of available CPU resources when querying the job log collection.
