Ok, the mystery deepens. I added the "strace -o /tmp/tracelog
-f /myscript" to the transport, and the script executes. However, after
removing it, I get the same error I reported earlier. I tried adding
"sh" to the front of the script and also got 127 error. Why would the
script execute without a problem while strace is there, but not at all
without it?

Thanks again,
