Hi!

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

After looking at the stack trace, I think this is https://fedorahosted.org/389/ticket/47391

The crash happened twice after about a week of running without problems. The crashes happened on two consumer servers but not at the same time.
The servers are running CentOS 6x with the following 389DS packages installed:
389-ds-console-doc-1.2.6-1.el6.noarch
389-console-1.1.7-1.el6.noarch
389-adminutil-1.1.15-1.el6.x86_64
389-dsgw-1.1.10-1.el6.x86_64
389-ds-base-debuginfo-1.2.11.15-14.el6_4.x86_64
389-admin-1.1.29-1.el6.x86_64
389-ds-console-1.2.6-1.el6.noarch
389-admin-console-doc-1.1.8-1.el6.noarch
389-ds-1.2.2-1.el6.noarch
389-ds-base-1.2.11.15-14.el6_4.x86_64
389-ds-base-libs-1.2.11.15-14.el6_4.x86_64
389-admin-console-1.1.8-1.el6.noarch

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.
One of the servers did not want to start after the crash,

Can you provide the error messages from the errors log?

so I have run db2index on its database. It's been running for four days and it has still not finished.

Try exporting using db2ldif, then importing using ldif2db.

All I get from db2index now are these outputs:
[09/Jul/2013:13:29:11 +0200] - reindex db: Processed 65095 entries (pass 1104) -- average rate 53686277.5/sec, recent rate 0.0/sec, hit ratio 0%

How many entries do you have in your database?


The other instance did start up, but the replication process did not work anymore. I disabled the replication to this host and set it up again. I chose "Initialize consumer now" and the consumer crashed every time.

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

I have enabled full error logging and could find nothing.
I have read a few threads (not all, I admit) on this list and http://directory.fedoraproject.org/wiki/FAQ#Debugging_Crashes and tried to troubleshoot.

The crash produced the attached core dump and I could use your help with understanding it. As well as any help with the crash. If more info is needed I will gladly provide it.

Regards, Mitja
