We recently upgraded from Centos 5.4 389-ds Version 1.1.2 to Centos 6.7 389-ds version 1.2.11
389-console-1.1.7-1.el6.noarch 389-ds-base-1.2.11.15-48.el6_6.x86_64 389-ds-console-1.2.6-1.el6.noarch 389-ds-base-libs-1.2.11.15-48.el6_6.x86_64 389-admin-console-1.1.8-1.el6.noarch 389-adminutil-1.1.19-1.el6.x86_64 389-admin-1.1.35-1.el6.x86_64
The setup has a single master, hub and 5 replicas. For some reason we are experiencing replication delays of upto 40 secs between hub and replicas. This did not occur in the old setup. At the time access logs showed an average of 1000 MOD operations per minute.
Some of our configured parameters:
nsslapd-maxdescriptors: 16384 nsslapd-max-filter-nest-level: 40 nsslapd-timelimit: 7200 nsslapd-sizelimit: 10000000 nsslapd-reservedescriptors: 92 nsslapd-maxthreadsperconn: 10 nsslapd-threadnumber: 120 nsslapd-dbcachesize: 4000000000 nsslapd-cachememsize: 20000000000
The systems resources on the Hub (CPU/memory/disk) look fine, so it must be 389-ds resources either on the hub or the replicas that must be causing the delay. Where should I be looking?
