[389-users] 389 directory server crash

Hi! We are having problems with some our 389-DS instances. They crash after receiving an update from the provider. 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, so I have run db2index on its database. It's been running for four days and it has still not finished. 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% 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. 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
