I'll have a look at this.

Apparently Adaptive Computing developers have fixed the problem and checked in
the change to subversion 2.4-fixes branch today. I do not know if the fix has
been merged into trunk yet. 

I asked that they keep community developers in the loop.

Really? Wish they would have posted as such in here.

A patch for 2.4.2 would be greatly appreciated.

a diff of stat_job.c is shown below:

This code used the length of pal->al_valln as an index into the attribute table
which would return the wrong attribute. In the case of mpiexec host_exec was
not found and the call failed. Removing this code solved the problem.

It's nice to see all of your feedback. We will do better to respond as we hear
you.

Fixed in 2.4-fixes and trunk

Ken, could you generate the patch using "diff -urN" so it could be used with
the patch command.
