This looks like <a href="https://fedorahosted.org/389/ticket/47409" target="_blank">https://fedorahosted.org/389/ticket/47409</a>
and <a href="https://bugzilla.redhat.com/show_bug.cgi?id=979169" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=979169</a><br>
<br>
Cause: Under certain conditions, with a mix of concurrent
search and update and outgoing replication operations, there
will be deadlocks in the changelog db, leading to error
messages like this:<br>
NSMMReplicationPlugin - changelog program -
_cl5WriteOperationTxn: failed to write entry with csn
(XXXXXXX); db error - -30994 DB_LOCK_DEADLOCK: Locker killed
to resolve a deadlock<br>
This is caused by a deadlock between the changelog readers,
writers, and main database writers.<br>
<br>
Consequence: Update operations will fail with the above
error message in the directory server errors log.<br>
<br>
Fix: A new configuration parameter is introduced:<br>
dn: cn=config,cn=ldbm database,cn=plugins,cn=config<br>
nsslapd-db-deadlock-policy: 9<br>
<br>
With the default policy 9 (DB_LOCK_YOUNGEST), the last
locker gets killed when there is a deadlock. In the case
that this is the changelog writer, the write will fail, and
the entire update will fail.<br>
<br>
Users who frequently see the above errors in the errors log
are advised to change this setting to 6 (DB_LOCK_MINWRITE)
will which instead kill the locker that has the fewest write
locks (that is, the changelog reader). The changelog reader
code has been changed to handle this deadlock condition and
retry. The setting can be changed like this:<br>
<br>
ldapmodify -x -D "cn=directory manager" -W <<EOF<br>
dn: cn=config,cn=ldbm database,cn=plugins,cn=config<br>
changetype: modify<br>
replace: nsslapd-db-deadlock-policy<br>
nsslapd-db-deadlock-policy: 6<br>
EOF<br>
<br>
You may ask why the default is not changed to 6. The answer
is that the setting will apply to _all_ threads, so that
changing this setting could cause regular search requests to
fail, if the directory server is under a heavy update load.
In our testing, we did not see this happen, but we cannot
guarantee that changing this value to 6 will not impact
regular search requests.<br>
<br>
Result: After changing nsslapd-db-deadlock-policy to 6,
updates will succeed and no longer cause errors like the
above.<br>

If you just want to upgrade only the LDAP server,
which is the component that I for sure know is out
of date, then yum update 389-ds-base.<br>
<br>
Or just "yum update" - in general I don't like
running "franken-systems" which have a mix of
up-to-date and out of date packages. Note that
"IPA server" is composed of several packages.<br>
<br>
You do not need to stop the server. yum/rpm
upgrade will restart as needed. If you want to
make sure, do ipactl restart after upgrade.

No, you just need to perform the same upgrade

You are using an older version of
389. The version on server2 is
older than the version on server1.
Can you upgrade and see if that
fixes your problems? Even if it
doesn't fix your problems, it will
be much easier for us to support.

You never
answered my
question
below. "Are
you sure that
this
connection is
a replication
session? Can
you post all
of the
operations
from the
access log
from
conn=936207?"<br>
<br>
In the future,
please avoid
spamming the
list with
large log
files. In
general, it's
better to
provide
excerpts from
the log files
showing the
problem, paste
them to <a href="http://fpaste.org" target="_blank">fpaste.org</a>, and post the
link to the
mailing list.
If for some
reason you
need to post a
large file,
please use a
file sharing
service and
post the link
to the file.<br>
<br>
Can you take a
look at your
errors log
from server 1
and server 2
and see if
there are any
relevant
errors?<br>
<br>
If I had to
guess, I would
say that there
is some sort
of network
error between
server 1 and
server 2 that
causes the
excessive
closed - B1.
Perhaps there
will be more
information in
the errors
log.

How do you
know server 1
is syncing
with server 2?<br>
<br>
On server 1
I'd run:<br>
<br>
ipa-replica-manage
list -v
`hostname`<br>
<br>
This will show
the
replication
status.<br>
<br>
And what does
ipactl status
show on server
2?<br>
