Description:
Active Directory Domain Services could not update the following object with attribute changes because the incoming change caused the object to exceed the maximum object record size. The incoming change to the following attribute will be reversed in an attempt to complete the update.
Object:
CN=Computer1,OU=Computers,DC=Careexchange,DC=in
Object GUID:
333333-f6b6-33e2-9333-333362ceed0
Attribute:

The current value (without changes) of the attribute on the local directory partition will replicate to all other directory services. This will counteract the change to the rest of the directory services. The reversal values may be recognized as follows:

In my Case its the Local Account Password Solution keeps the unlimited password history. Causing to exceed the maximum object size.
Once i clear the attribute, Solve the replication issue.
How did you know and/or come to the conclusion it was what you found?

What object attribute did you clear?
In my case it was ms-Mcs-AdmPwdHistory attribute
Just had this issue as well. What I did was check the GUID on the object that was generating the event (in server roles > ADDS ):
1. Get-ADObject $GUID -Properties *
2. Check all attributes that are lengthy (select-object -expandproperties Attributename)
3. Set-ADObject -Clear $Attributename
This resolved our replication issues at next replication interval.
Hope this helps.
Also, thanks for the info in this post Satheshwaran!
