The application periodically calls the libc system() routine. The system() routine just calls a simple external bash script. The application is a SCHED_OTHER application with PI mutexes. I think that the problem is caused by the system() routine. The following is a dump of the stdout made with kernel version 2.6.19.1-rt15. But 2.6.20-RC5-RT10 has the same problem.
