A wfong is currently running TVSRV1 and TVSRV2 processes with no 
corresponding socket in /tmp.  I lack privilege to kill these - I told 
him yesterday to kill them but apparently he did not.  I suspect that he 
is exiting aips without using KLEENEX and is killing the TV with a kill 
-9 (the X in the upper right corner is often equivalent).  A kill -9 
does not clear up everything since it says to avoid using any abort 
handler (which is useful for XAS especially).  If you start aips with 
tv=local:n  with n > 2 you should get a working TV - but please find 
wfong and get him to kill these processes.  You do have sockets for 
local TV #1 other than for the TV lock daemon as the above error 
messages say.
