Description
Activating query profiling on the system level in combination with high user concurrency could cause the database to be overloaded. In these cases, users may notice the following symptoms:
- unresponsive system
- reduced query concurrency
- very high login times
Workaround
Turn off query profiling on the system level and restart the database. You can activate query profiling for a session when needed.
Fix
The database will remain responsive in these scenarios.
