GETMAXVERSION: The lineage parameter is shorter than the minimum required size.

Hi all,

Publisher sql2008, , ~400 subscribers using SQL2008 Express, merge replication pull.

I'm seeing this error in msrel_errors table :

error_code 21512 

error_text GETMAXVERSION: The lineage parameter is shorter than the minimum required size.

Happening for a 8 of the subscribers (so far).  Usually they hit this error twice, and the third sync succeeds.

I'd like to understand whether this is a benign issue, or whether it is an indication of a more serious underlying problem.  Googling this message returns very few results, and nothing of any use.  Can any advise ?

Thanks !
