> 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.
