I'm trying to implement syncrepl in my openldap 2.3.35 without
sucess. I tryed many (I sed: MANY) times to slacat, slapadd to
slave for syn ldap servers, but for some reason with I don't know,
the slave lost the sync.
Then I have to do the same thing ate night:
- stop ldap master;
- slapcat master
- slapadd on the slave;
- start master and start slave
This works about one hour, in the morning wasn't syncing again.
If i restart the slave ldap, then the changes on the master is
replicated, but stops to sync "on line" after this.
I had troubles like this when the replication load was very large.
The replica encountered a time limit and its search aborted.
Unfortunately, the only way to know for sure is to add logging to
syncrepl.c.
Without that you can only guess. I have done that with 2.4.4 test
release, and
I just now posted a patch: http://www.openldap.org/its/index.cgi/
Incoming?id=5014
Since it won't apply to 2.3, I append an untested patch for 2.3.24.
