In fact the semaphore modules are built in now. I did some debugging and the
error happens in the code at SemSet.c line 25
for (i = 0; i < sets; i++) {
int id = semget(IPC_PRIVATE, MAX_SYSV_SET_SIZE, IPC_CREAT
| S_IREAD | S_IWRITE); //SEM_R | SEM_A);
if (id == -1) {
the first semget(i=0) succeeds and the second fails with an errno ENOSPC which
from the man page implies a resource issue of some kind.
[ENOSPC] Insufficiently many semaphores are available.
[ENOSPC] The kernel could not allocate a struct semid_ds.
I guess the freebsd limits must be different to the original development
environment.
