Okay, I got the issue, basically we are dropping the database buffers
but not unregistering the existing sync request for database buffers
w.r.t old tablespace. Attached patch fixes that. I also had to extend
ForgetDatabaseSyncRequests so that we can delete the sync request of
the database for the particular tablespace so added another patch for
the same (0006).
I will test the performance scenario next week, which is suggested by John.
