Possibly it's trying to output to stdout or stderr and cannot due to tty/pty being taken out underneathe it. Other *IX people here can give you some alternate advice, but I'd recommend these options: 1) Under sh/bash: myprogram 1>/dev/null 2>&1 & (or replace /dev/null with a logfile of your choice) 2) Use dtach (ports/misc/dtach) and detach your program. http://dtach.sourceforge.net/ 3) Use GNU screen (ports/sysutils/screen) and run your program within that. http://www.gnu.org/software/screen/ -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
