Re: High memory usage in provider server
I think the real question here is: what replication strategy will make
supplier server consume less memory: Syncrepl - pushing records from
supplier to consumers ? Consumers pulling records from supplier via
syncrepl ? Delta-syncrepl pushing records from supplier to consumers ?
Consumers pulling records from supplier via Delta-syncrepl ?

Hi there !
We are using two LDAP servers providers (openldap 2.4.23) in mirror
mode: one just to receive modifies and the other, just to be
"consumed" by 11 consumer servers. Both servers have almost 1MM
objects with 10kb in size each. Id2entry.bdb has 21Gb and dn2id.bdb
has 286Mb in size. When checking the first server we note that slapd
is using ~4.0Gb of memory (RES). The problem is the second server,
where all 11 consumers points to. Slapd in this server is using
~18.0Gb of memory (RES). We are using syncrepl to synchronize the 11
consumers with the 2nd server (RefreshandPersist). Openldap´s compile
options are identical in both servers. Same for OS (Fedora 13 - x86_64
fully updated) and packages.
Any ideas to reduce memory usage in the second server ?
