In F15_64, on starting SysV myDaemon in level 3, with S99myDaemon rtn = pthread_create() fails with: rtn=1=Operation not permitted man pthread_create says this means: No permission to set the scheduling policy and parameters specified in attr. This happens for: policy = SCHED_FIFO policy = SCHED_RR This code works if, after boot, I start it with: /etc/init.d/myDaemon start and starts on boot in my old CentOS 5 box. Thanks for your suggestions.
