I hate to waste developer and port maintainer time, so apologize in advance
for this long message. Anyways, if there is anything useful I can do to help,
please let me know.
I am puzzled about why I don't seem to have any problems with OpenLDAP
2.3.33p2 on
kern.version=OpenBSD 4.2-current (GENERIC.MP) #0: Thu Dec 27 13:53:57 CST 2007
[EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC.MP
with
db-4.6.21 Berkeley DB package, revision 4
openldap-server-2.3.33p2-bdb Open source LDAP software (server)
The OP said that his ./configure command was almost the same as what I did
above but did not bother to say what the difference was. I followed the
settings that Marc Balmer had in ports and so I wonder whether that is why I
haven't seen any problems yet.
Usually, I have problems even when no one else has any issues so I am
surprised to not have had a crash or any problems at all when I should have
had seg faults! I am using all the samba-related schemas PLUS slurpd and I am
still not seeing segfaults with OpenLDAP 2.3.33p2 and DB 4.6. I am not new
to OpenBSD (have used it since 2.8 and have the CD's to prove it :) but don't
know whether I have somehow made a mistake in compiling userland or whether
there is some other issue involved that is making use of older versions of
DB4. But don't see any traces of it on this server. This is on one of my test
servers and I have followed -current on it on an ongoing basis.
I ran it with a standard reboot on my test server with slapd starting as
follows.
Dec 31 06:54:11 web1 slapd[16122]: slapd stopped.
Dec 31 06:54:19 web1 slapd[2920]: @(#) $OpenLDAP: slapd 2.3.33 (Dec 12 2007
04:19:57) $
@i386new.ports.openbsd.org:/usr/obj/i386/openldap-2.3.33-bdb/build-i386-bdb/servers/slapd
Dec 31 06:54:19 web1 slapd[2920]: slapd starting
.
.
Dec 31 17:29:30 web1 slapd[2920]: daemon: shutdown requested and initiated.
Dec 31 17:29:30 web1 slapd[2920]: slapd shutdown: waiting for 0 threads to
terminate
Dec 31 17:29:30 web1 slapd[2920]: slapd stopped.
Then on December 31st evening, I started slapd with
/usr/local/libexec/slapd -h "ldap://127.0.0.1 ldaps:///" -d -1
and it ran till this morning -- no seg faults.
I rebooted the server again
Jan 2 09:56:59 web1 slapd[20923]: @(#) $OpenLDAP: slapd 2.3.33 (Dec 12 2007
04:19:57) $
@i386new.ports.openbsd.org:/usr/obj/i386/openldap-2.3.33-bdb/build-i386-bdb/servers/slapd
Jan 2 09:56:59 web1 slapd[27144]: slapd starting
Thanks again for all the great ports/packages.
