FRSchedulerService.exe is using high CPU utilization in ITSM 7.x. The FRSchedulerService.exe is consuming 100% CPU. There are a number of scheduled jobs but as far as you are aware none should be running during business hours.
Usually this happens, if the number of schedule jobs are happening at the same time.
Stagger the jobs and make sure the scheduled jobs are done when there is less activity on the application. For Example at night.
