Well I thought it was a bit obvious in the replmetadata as some 
attributes modified in January have the same local usn as the one that 
were just modified.

Nevertheless I made one more trace and got this:

blob                     : DATA_BLOB length=4

Here we just change instance type and description and one more time I 
have the following replpropertymetadata.

Any clues ?
