[Freeswitch-users] Failed to set SCHED_FIFO scheduler

Hi, Please find my below deployed environment: Environment: Microsoft Azure OS: CentOS 7.0 (64 bit) FreeSwitch Version: 1.6.6~64bit ( 64bit) I installed FS and able to make test calls. When I execute "systemctl status freeswitch" command, I am seeing below errors: *ERROR: Failed to set SCHED_FIFO scheduler (Operation not permitted)ERROR: Could not set nice level* Can anybody tell me what could be the issue and how to solve this? Thanks in advance, Chandra.
