Re: slapd shuts down for no reason
Check for OOM messages in your system log. The OOM manager will kill whatever the next process is to allocate memory when it runs out regardless of how much or little that process is using. Whatever the case there is no slapd bug here. Something on your system is specifically telling slapd to stop and it is doing as instructed.
