Hi!<br>
<br>
We are having problems with some our 389-DS instances.
They crash after receiving an update from the provider.<br>

After looking at the stack trace, I think this is <a

Yes, it looks like it might be it. When CONSUMER_ONE crashed for
the first time, the last thing replicated was a password change.<br>
Do you perhaps know, where I could get a 389DS version for
Centos6 that has the patch? The ticket says it was pushed to
1.2.11, but would seem that our 1.2.11.15-14 is still an
unpatched one and the repositories do not have any newer
versions.<br>
</blockquote>
<br>
Is that the 389-ds-base that is included with CentOS6?<br>
</blockquote>
Yes, the 389-ds-base-1.2.11.15-14.el6_4.x86_64 and
389-ds-base-libs-1.2.11.15-14.el6_4.x86_64 are from the official
Centos6 updates repoository.<br>
389-ds-base-debuginfo is from <a class="moz-txt-link-freetext" href="http://debuginfo.centos.org/6/">http://debuginfo.centos.org/6/</a><br>
The rest are from epel.<br>

We are in the process of replacing the Centos 5x base
consumer+provider setup with a CentOS 6x base one. For
the time being, the CentOS 6 machines are acting as
consumers for the old server. They run for a while and
then the replicated instances crash though not at the
same time.<br>
One of the servers did not want to start after the
crash,</blockquote>
<br>
Can you provide the error messages from the errors log?<br>

I have attached error logs from the provider
(2013-06-27-provider_error) and the consumer

The export process hangs. After an hour strace still shows:<br>

Are you using db2ldif or db2ldif.pl? If you are using
db2ldif, is the server running? If not, please try first
shutting down the server and use db2ldif.<br>

If db2ldif still hangs, then please follow the instructions at

I was using db2ldif with the server shut down. I tried it again
and it hung. The LDIF file was created but its size was zero.
The produced stack trace is attached as

Can provide a stack trace of the core when the server
crashes? This may be different than the stack trace
below.<br>

The last provided stack trace was produced at the last
server crash. I will provide another stack trace when
CONSUMER_ONE crashes again. Currently it refuses to crash at
initialization time and keeps running.<br>
