Hello, I'm trying to port RPL/2 (http://www.rpl2.net) to OS/2 and I don't understand OS/2 semget(). RPL/2 uses POSIX semaphores. I have written a minimal library that emulates POSIX semaphores with SysV ones. I have tested this library on several Unix systems without any trouble. On OS/2, semget() always returns -1 and I don't understand my mistake. int sem_init_SysV(sem_t *semaphore,...

.... Unfortunately it made no difference. :-(. I added some debugging code and looked what happened : -------------------------------------------------------------------- DEBUG(4,("Trying sysv shmem open of size %d\n", shm_size)); /* first the semaphore */ sem_id = semget(SEMAPHORE_KEY, 0, 0); if (sem_id == -1) { if (read_only) return NULL; hash_size = SHMEM_HASH_SIZE; DEBUG(4,("semaphore : initial hash-size = %d \n", hash_size)); while (hash_size > 1) {...

Hello together, since today morning I have an massive performance issue with samba 2.0.6-3 (Debian - Testing-Tree) in my samba production environment. Samba responds very slowly within the logon process (2-3 Minutes for each line in the netlogon.cmd). Later during normal operations opening from files works very slowly and often breaks connection. There is no cpu or memory load on the system.
