shm_open (667) & locking_init(174), not 2.3.xx kernel
This weekend, we upgraded our server to Linux-Mandrake 7.1, which uses
a (slightly customized by Mandrake) 2.2.15 kernel. Since then, users are
unable to log in, and log.smb shows
locking/shmem_sysv_shm_open(667). Can't create or use use IPC area. Error
was File exists
locking/locking.c:locking_init(174). ERROR: Failed to initialise share

semget() failed
...s returns -1 and I don't understand my mistake.
int
sem_init_SysV(sem_t *semaphore, int shared, unsigned int valeur)
{
int ios;
union semun argument;
if (shared != 0)
{
return(ENOSYS);
}
(*semaphore) = semget(IPC_PRIVATE, 1, IPC_CREAT | IPC_EXCL | SEM_R
| SEM_A);
if ((*semaphore) == -1)
{
// Always true with OS/2 (libc 0.6.3)
return(EINVAL);
}
argument.val = valeur;
ios = semctl((*semaphore), 0, SETVAL, argument);
return(ios);
}
Any explanation ?
Thanks in advance,

how to start liveice with screen?
Moin,
I installed liveice as well as 'screen' at a debian maschine, both
applications are running fine. But when I try to start liveice in a 'screen'
environment then the liveice process ends without an error message:
$ /usr/bin/screen -dmS liveice /usr/bin/liveice
A prefixed 'strace -f' shows me:
[pid 5614] old_mmap(NULL, 167936, PROT_READ|PROT_WRITE,
