[389-users] 389-Directory/1.3.1.6 cannot setup replica

Wed Nov 5 19:53:58 UTC 2014

Hi, 

i'm having the same problem. I'm in the process of migration from our 389DS v1.2.10.25/CentOS5 to 389DS on CentOS 7. Everything is working fine on standalone servers but the replication (especially online initialization). It stucks _each time_ during the online initialization with SSL/TLS (and sometimes without SSL/TLS). And exactly with the same error messages as you describe. 
The network problems in my case are excluded - i used both virtual machines on the same ESXi in the same network and/or physical servers, the results are the same. 
I've tried compiling all the branches latest available (tags 1.3.2.24, 1.3.1.22, 1.3.3.5). In all the cases the result was the same. The server pushing the updates just gets stuck at some random number of entries sent to consumer (we have ~30000 entries, it gets stuck at random somewhere from 1200 to 25000 entries, the entries stuck have nothing particular in size, it's completely random). 
1.2.10.24 compiled with compat-db-4.7 on CentOS 7 has the least of these problems (and the initial replication is 10 times faster - it takes 8 seconds instead of 80 for 1.3.x!). I've been using 1.2.10.24 on CentOS5 compiled with mozilla ldap labraries and 1.2.10.23 obn CentOS 7 compiled with opendlap librarires. The first one had no problems at all to push the initial replication, the second one had intermittent problems, but much less than v1.3.x 

I've noticed that this problem is getting worse (or simply appears) if : 
* the replica is be of type 3 (multi-master), with replication agreements in both directions 
* our schema has several additional attribuites, it may be also important 
* if the virtual machine has only one CPU. Adding a second CPU increases the number of transferred entries before the initialization gets stuck. So it may me some thread/transaction contention or deadlock. 
* if the replication agreement uses SSL(port 636) or TLS(port389). Using port 389 with LDAP protocol instead of TLS/SSL increases the number of transferred entries before the initialization gets stuck. Sometimes the initialization even ends successfully in this case. 
* decreasing nsslapd-db-checkpoint-interval (say, to 5 seconds) also gets the problem worse 

When the on-line intialization is finished (if it finishes), there are no problems. I think it is related to the volume of data transferred, so small incremental updates do not generate any problem.... 
If necessary, i will make any debugs/tests - it is a critical element of our infrastructure, so i'd like this problem to be resolved...
