Hung uuxqt processes

[Dominick Samperi]

Does anyone have any idea how a command started by uuxqt can freeze, doing
nothing, while the data to be processed is sitting in the uucp spool
directory (that is, the D.xxx and X.xxx files are there, and they are
in good shape)? The command in question is one that I call 'uucpio', it
executes system("compress -d | rcpio -icdum"), and as the 'ps -ef' listing
below shows, the necessary processes are started, but they do nothing; the
same listing results if ps is run time and again, yet there is no system
activity. (rcpio is cpio modified for remote use.)

I'm running this under Microport's System V/AT. Any comments would be
greatly appreciated.
