I see that I'm outdated in my tuning as per
http://wiki.zimbra.com/wiki/OpenLDAP_Performance_Tuning.
I'll do these changes and observe the servers.
In the mean time a new observation regarding syncrepl is that if I do
ldapmodify for 5 - 10 entries in one go the changes get replicated but if
I change about 300 entries in one go, then some entries do not get
replicated on some servers. These changes dont get replicated until I
change those entries again.
Does this indicate provider resource problem or consumer resource problem
( or normal behaviour ) ?
