Data Yet Another nohup question...
I am running a cobbled upnp sample program from /etc/rc.local with nohup. It is fine except it uses almost 90% CPU. If I stop it and run it from a shell it uses essentially no CPU as it should. It does have a little debug shell and in debugging I noticed a huge nohup.out file that it is apparently in a loop saying more or less "bad command".

So, the program thinks it is getting input and responding. Although there is no input that I know of and redirecting stdin doesn't help.

Any ideas on what might be going on or a simple way to fix it?

(I tried `nice` might mitigate the scheduling with other tasks but doesn't solve the problem)

Thanks,

jv

nohup

NOHUP(1)							   User Commands							  NOHUP(1)

NAME

       nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS

       nohup COMMAND [ARG]...
       nohup OPTION

DESCRIPTION

       Run COMMAND, ignoring hangup signals.

       --help display this help and exit

       --version
	      output version information and exit

       If  standard  input is a terminal, redirect it from /dev/null.  If standard output is a terminal, append output to 'nohup.out' if possible,
       '$HOME/nohup.out' otherwise.  If standard error is a terminal, redirect it to standard output.  To save output to FILE, use 'nohup  COMMAND
       > FILE'.

       NOTE: your shell may have its own version of nohup, which usually supersedes the version described here.  Please refer to your shell's doc-
       umentation for details about the options it supports.
