Hi Rich,

Do you see seg fault messages in /var/log/messages?

Sure: ns-slapd[13737]: segfault at 00000000000000bc rip 0000003abb420375 rsp 00000000580d85d0 error 4


The directory server dumps core in the log file directory, which by
default is /var/log/dirsrv/slapd-INSTANCE

Yes, it is the same as working directory:
# ls -l /proc/`pidof ns-slapd`/cwd
lrwxrwxrwx 1 root root 0 Sep 7 17:12 /proc/18721/cwd -> /var/log/dirsrv/slapd-ds1


Is the crash easily reproducible?

No, it isn't. It seems random, but I can simulate a crash with kill -QUIT.

I tried killing a simple `sleep 10`:

# ulimit -c unlimited

# sleep 10 &
[1] 19726

# kill -QUIT 19726
[1]+  Quit                    (core dumped) sleep 10

# ls -l core.*
-rw------- 1 root root 290816 Aug 31 08:52 core.1008

But if I kill -QUIT ns-slapd no file is created.

Thanks,
	Dael Maselli.
