I am able to execute my script fine at the command prompt (i.e. ./ScriptName.ksh. But, it fails when I run it in the background using nohup (i.e. nohup ./ScriptName &
It outputs:  + Stopped (SIGTTOU) nohup ./ScriptName.ksh &
The nohup.out file logs: stty: setattr: There is an input or output error.
Any ideas what is causing this?
