We are using 2.6.28.8 and xenomai 2.4.7 on a AMCC PowerPC 460EX platform
and getting
the following message.
Xenomai Posix skin init: pthread_setschedparam: Resource temporarily
unavailable
It takes quite a while for this to happen. The /proc/xenomai/heap value
for used keeps increasing.
Once the "used" gets very close to "size" the user space xenomai
applications can no longer run.
I have isolated the problem to opening and closing shared memory areas.
shmfd = shm_open(RTL_SHM_NAME, O_CREAT | O_RDWR, 0777);
if (shmfd == -1) {
printf("Gp Share mem Open, Err: %d Msg: (%s)\n", errno,
strerror(errno));
return -1;
}
ftruncate(shmfd,MAKE_PAGESIZE(sizeof(struct SHM)));
pshm = mmap(NULL,MAKE_PAGESIZE(sizeof(struct SHM)),PROT_READ |
PROT_WRITE,MAP_SHARED, shmfd,0);
munmap(pshm, MAKE_PAGESIZE(sizeof(struct SHM)));
close(shmfd);
shm_unlink(RTL_SHM_NAME);
The above calls are in a shared library that an applications call.
