The limitation is that UBIK update transactions are "whole
object", not incremental. At about the 1000 user range the update
transactions begin to take longer than 60 seconds, so the ptservers
lose quorum and have to re-elect and sync before write operations can
take place again. This makes updates involving those groups extremely
painful. Depending on the speed of your database servers the limit may
vary. UBIK was not designed for large object updates.
There is the possibility of constructing the DB0 file for the
ptserver offline and snapping it into place on your production
servers, thus bypassing the UBIK update mechanism. I think MIT could
get more specific - we've never had to do that.
Short answer is: no, don't if you can possibly avoid it.
