RE: openldap versions and silent exit

Wow, I haven't seen anything like that but I'll keep a look out for the size of the process.

Unless I restart it periodically, the slapd process will grow to the
limit of available memory (out of a total of 1 GB RAM per server,
in this case). I've definitely correlated the process growth to
search operations. Rate of growth depends entirely on the number
and type of search operations processed by slapd.

At the moment, I have a cron job check the process size in the late
night hours and restart slapd if it exceeds 30% of total memory. (I
could have let it get larger, of course, but didn't know what impact
that might have on performance or stability.)
