Thank you very much Eli for concidering my issue. Here is my scenario...

 

I couldn’t find any abnormality in log files and also I never seen any deletion logs in the server. Slapd will go for hang and some ID`s will get disappear same will be replicate to slaves too. Mainly Groups and Computer accounts

Have you tried raising the loglevel?

Are the schemas the same between the servers?

Is time in sync between the servers?

What versions are you dealing with?

You don't provide a lot of info and most of us are not clairvoyant....

Regards,

Eli
