We use terminal servers instead of HPSIO/621 since it gives better functionality
we even use them to allow telnet into no-netowrk towers/devices.

The 5.3 towers ( esp. 5.3.2 / 1.01.01 etc ) are especially talented at
silent deaths !! We find this on NFS , TCP ( this also relates to speed),
printers and modems !! Our problem ,and your's 'sounds' the same, is stream
tuning , check strstat ( from shell or crash ) and tune accordingly.

You may also not be aware that all tty tallies etc are now turned of, this
really doesn't apply in this case but is well worth knowing.

If you are running out a stream blocks you will get a silent death as you
describe. We have some 'specs' etc in to deal with the problem of not
being notified.

Hope this helps ( somebody :-) ) 

Ian
