Log shipping error - database in use

I am using MS builtin log-shipping functionality in
SQL2000.
My log shipping maintenance plan has a secondary load
state of 'standby' mode. And I have selected
the 'terminate users in database' option - however,
occasionally my log-shipping job is failing with '3101 -
database in use' error.
However, I thought that by selecting 'terminate users in
database' option - this should never happen ?
Has anyone seen anything similar before ?'terminate users in database' will not work always and
does not guarantee anything, a terminated process may drop
into a rollback mode and then it could take a long time to
finally get disappeared.
