Ecasound produces output when it works, but when it doesn't, it produces

I didn't really follow this, but typically you can debug exec problems
from the command line by switching to the web server user id and running
the exact same command.

Yes, but that's been done. Since these are shared servers, on one I am
logged in as the user the web server is running as, on the other I can't

capture them. If permissions caused this, it would fail every time, since
I am assuming that you get hold of the file through uploading it, correct?
So, when it fails maybe another upload (i.e. script invocation) is happening
and the previous file gets lost/corrupted/whatever. Try to move the file to
another dir (maybe /tmp) with a random name and see what happens.
php places uploaded files in the /tmp directory with a unique name, and
when I copy them to my directory, I also guarantee a unique name for them.
I have verified that this is all working. I've patched this with a cron
job that runs every minute, but it really should happen in php, so that

I have a question on an exec() command, if I would like to switch user right on

example: on the UNIX shell will be like below

You have to be root to add a user to the system...and just a heads

security implications alone make me cringe.
