Noticed it first with 5.1.

Currently we're running 6.0 MP4.   Now that you mention it I won't swear
I've seen it since we went to 6.0 MP4.  (But I also won't swear I
haven't either.)   Since it wasn't an every day occurrence we wouldn't
have noticed it "going away" after the 6.0 MP4 upgrade.   

It was just something we saw once in a while we would live with it until
end of a week when we could bounce daemons on the master.

One thing we did notice with 6.0 MP4 in relation to RMAN - we had
upgraded the master but not one client on one DB server we were backing
up with RMAN.  We were seeing things like 25 (communication error) and
52 (tape error) on occasion.  Updating the client to 6.0 MP4 on the
database server being backed up seems to have stopped those.  (The 52
was really odd because we were actually using a DSSU rather than a tape
as the backup device and had never seen a 52 on that before the upgrade
to 6.0 on the master.)  Before the upgrade of the client backups were
completing most days so it was totally incompatible.

What version are you running?

Does it occur with 6.0MP5/6.5.x?

Justin.
