[Fedora-directory-users] Problem with Massive Replication Agreements

Hi all,

I have a distributed Directory Service on 25 servers with FDS 1.0.4. The
replication configuration it''s some complex:

- One HUB server with 26 Databases(26 enabled Replicas)-> 25
HUB-Replicas with 24 replication agreements and one Multimaster-Replica
with 26 replication agreements. Total replication agreements in this
server it''s 626 replication agreements.

- 25 Supplier (on our database) with Hub server and consummers (for
others databases) of Hub server.

When i try to configure (automatically by script) this 626 replication
agreements (on HUB server) i show this
errorlog(/opt/fedora-ds/slapd-prueba/logs/errors) for each new
replication agreement after 250 replication agreements aprox.:

[22/Jul/2007:20:55:52 +0200] NSMMReplicationPlugin -
agmt="cn=prueba1-prueba2" (prueba1:636): Unable to create protocol
thread; NSPR error - -5974, Insufficient system resources.

Exist some FDS limitation about massive replication agreements? or some
FDS performance settings (maximun entries, caché,look-through limit,
size limit, file descriptors,connection management...)?

How can i solved this problem?

thanks,
