The following two more statements are not printed.
csultra05:Hello world from 6

This behavior I observed on my Linux cluster too.
Hi Ravi -
Thanks for the bug report. We've determined that there is definitely
a problem with starting applications from an app context file on the
trunk. The issue appears to be a regression that slipped into our
development trunk, but is not in our release branch. I've passed the
bug report on to the author of that code and he is looking into the
issue, but I don't have a timeline to having the issue resolved.
For good news, the issue with Solaris has been resolved in the v1.0
release branch and the app context bug does not exist there. So the
upcoming Open MPI 1.0.2 release (and the currently available Open MPI
1.0.2a10 alpha release) should work properly for your environment.
Hopefully now that we have some Solaris users regularly testing Open
MPI, your experiences with the release branches on Solaris should be
much more stable :).
Brian
