Hi Scott, I do not see anything in error log, The print line before and after the command also works fine,The webserver has permission to run the command since I can execute the same command using backtick like `/tmp/in_out_err.pl` Do we need to configure anything so that apache can start executing the Apache::SubProcess package ?

If you put a print line before and after running the command, do you see either of them? Does the Web server user have permission to run the command? Is autoflush turned on for $in_fh? Does the running program flush its output immediately? Good luck! ----Scott.
