LDAP Synchronization Running Very Very Slowly

The initial configuration and import of the LDAP into confluence ran really fast (~2 hours). We had to update the field mapping to remove the displayName (our ldap displayName field does not contain a readable name). To do this we entered a field name that does not exist in the LDAP (ex: "User Display Name Attribute:*" = "dummyValueThatDoesNotMatchLDAP"). After making this change the LDAP starting a full sync and ran well for a number of hours. However it has been slowing down ever since. Currently we are processing roughly 4 users a minute. At this rate it will be another 4 days until the sync finished (We started this 4 days ago). Also the processing rate is slowing so I'm concerned it will not finish. Our CPU usage is now almost maxed out. 

I'm seeing this in the log files:

Hi Stephen, 

Thank you for your quick response! The normal syncing to confluence from our LDAP was working great. However a change in the "User Schema Settings" caused the syncing to run a crazy long time. In our non-production environment we tested this and once the updated schema sync finished the normal syncing worked great. Is there something we can do to get through the update sync?

Thank you,

-Tim Patton
