[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,

Re: [Fedora-directory-users] Problem with Massive Replication Agreements
The message tells you that the server failed to create a thread because the OS wouldn''t let it. Typically this happens either because there''s some OS limit that needs to be increased, or because the thread stack stride is very large and you''re running a 32-bit server (the fix for that is to reduce the stack size).

Re: [Fedora-directory-users] Problem with Massive Replication Agreements
I''ve installed FDS over Centos 4.5. How can i modify this OS limits or thread stack in Centos (RedHat)? and then probe the replication configuration. thanks, El dom, 22-07-2007 a las 11:09 -0600, David Boreham escribió:> The message tells you that the server failed to create a thread > because the OS wouldn''t let it.

Re: [Fedora-directory-users] Problem with Massive Replication Agreements
I solved the problem, I reduced the stack size to 1024 (it was 10240) with ulimit -s 1024.
