Fascinating. It would be interesting to know exactly what Veritas is
doing that causes the problem. Do any error messages show up in the
postmaster log while you are doing the above?
I'm still quite concerned about the health of your database, btw.
I can't see any reason to think that whatever interference is going
on would corrupt only indexes. There may be problems accumulating
in the table files as well :-(
