I don't want to crowd the list up with dead ends, so I was trying to
respond only to you.
I'm not calling a php program from exec, I'm calling ecasound and
convert. For example, in the php code:
exec("convert $internalpath/$filename -resize
{$thumbWidth}x{$thumbHeight} $internalpath/$thumbname", $out, $err);
doesn't always work, but with variables substituted on the command line:
bash:~> convert futon.jpg -resize 240x180 futon_thumb.jpg
will always work.
The same is true, on a different server, of my exec that calls ecasound,
an mp3 processing utility. Both of these could conceivably use a lot of
resources, which is why I think php is killing them off some of the time.

Depends on the install. My cli uses a different php.ini than the web one.
Did you check permissions? Does the user which your web server is running as
have execute permission on the app?

I have two programs on two servers, and they both have similar problems.
In each one, I use 'exec' to call a helper program. In one case, it is
ecasound, which I use to resample an mp3. In the other, it is convert,
which creates a thumbnail of a very large image the user has uploaded.
In both cases, the exec command fails. Not all the time, but some times.
In both cases, the command that is being called by exec will work fine at
the command line. I assume that there is some memory / resource limit
that is being breached when this happens, but I don't know what it is, or
how to tell php to allow my programs to run. Any ideas?
Or is save mode on?
