Folks,
I have recently upgraded my ldap servers (RHEL6, locally built RPM) from 2.4.42 to 2.4.44. After several days of chasing why our nagios checks for syncrepl performance were reporting long delays, I gave up and rolled the primary server back to 2.4.42. This
week I have built a primary and replica on RHEL7 with 2.4.44 (again locally built) and have just discovered through some intensive testing and log crawling that the syncprov log entries (with loglevel sync) show up lacking the csn about every hour, and if
there are outstanding changes to be replicated when that happens, the syncrepl check on the replica server starts reporting it has fallen behind. This behavior does not exhibit with the 2.4.42 code base.
Is this the new normal? Is there something (that has not yet made it into the guide) that I need to change in my syncprov/syncrepl configuration to get around this?
This is a “normal” syncprov log entry:
Apr 1 18:18:40 ldap7p slapd[10061]: syncprov_sendresp: cookie=rid=100,csn=20160401221840.842942Z#000000#000#000000
This is one of the new ones:
Apr 1 18:14:28 ldap7p slapd[10061]: syncprov_sendresp: cookie=rid=100
