We have an OpenLDAP 2.4 cluster of three nodes configured in
and accessed through a VIP in round-robin. The three machines run RHEL7.
What could be the cause and what could we do to further troubleshoot the
issue? Thanks in advance.
a) Don't use the outdated builds from RedHat. You generally have the
following choices here:
1) Build OpenLDAP yourself
2) Use a free replacement, such as Symas' OpenLDAP for Linux
>) or the LTB project's OpenLDAP build
3) Obtain a commercially supported version of OpenLDAP, such as Symas
OpenLDAP Gold (<https://symas.com/symasopenldap/>
;. There is also optional
commerical support for Symas OpenLDAP for Linux
b) Use delta-syncrepl, not standard syncrepl.
c) Ensure that in addition to stats logging you also have sync logging
enabled, otherwise you'll never be able to tell what's occuring.
Also, you fail to note your configuration settings for the syncprov
overlay, which is rather critical to note as well. For example, you may
have a low sessionlog value set, which can cause all sorts of havoc with
standard syncrepl, especially in older releases.
