    Description

      sqstart failed on CentOS.
      The Monitor process abort in CProcessContainer::CProcessContainer() due to failed to create semaphore.

      //create & initialize existing semaphore
      char sem_name[MAX_PROCESS_PATH];
      snprintf(sem_name,sizeof(sem_name), "/monitor.sem.%s", getenv("USER"));
      Mutex = sem_open(sem_name,O_CREAT,0644,0);
      if(Mutex == SEM_FAILED)

      { char buf[MON_STRING_BUF_SIZE]; snprintf(buf, sizeof(buf), "[%s], Can't create semaphore %s!\n", method_name, sem_name); mon_log_write(MON_PROCESSCONT_PROCESSCONT_3, SQ_LOG_ERR, buf); sem_unlink(sem_name); abort(); }

      sem_name is not initialized and snprintf will not add \0 after copy required bytes.
