This is a little odd:

(gdb) run -d 255
Starting program: /usr/sbin/slapd -d 255
must compile with LDAP_DEBUG for debugging

*** "CRASH" ***

Program exited normally.
(gdb) ba
No stack.

I have been running a script, while ldapsearch -x; do sleep 10; done, that
eventually crashes slapd. But gdb provides little feedback, as noted
above.

I have just reconfigured slapd to use one thread and removed all indexes
from the configuration. So far, I have not seen a crash. I am no using two
clients to query slapd and have removed that sleep statements so that the
server is continuously queried. I've been running this for about one hour
and will report back if there are any negative results.
