The XAS program disconnected from AIPS for some reason during the
middle of the TVLOAD ("connection reset by peer") and the low level
routines return a 333 or 444 as TV is broken.  After this happens can
you do further TV verbs like TVINIT?  Or has XAS more or less gone
away?  Is this an Inet TV or a local TV and was it started by the same
account as is being used for user number 666?

I assure you that the user number is unrelated to the error message
directly, but there could be account privilege interactions I suppose.
Usually they would appear as a failure to open the TV to start with
rather than a break in the middle.

Are you trying to load a particularly large image are something like
that when this happens.  I cannot think of any reason why the
connection should reset but perhaps some untrapped error could occur.
