liu ming commented on TRAFODION-1865:
-------------------------------------
The root cause is incompatibility of glibc from CentOS 6 to CentOS 7.
It has no relationship with uninitialized buffer.
The right solution is to build trafodion binary using gcc 4.8 under centOS 7 to
run it on CentOS 7.
So close this jira now.

> 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.
