Subject: Re: [MTT users] MTT server side problem
From: Josh Hursey (jjhursey_at_[hidden])
Date: 2008-05-20 10:00:00


I just got back from travel this morning. I reviewed the patch and it
looks good to me.

I updated the ticket:
   https://svn.open-mpi.org/trac/mtt/ticket/357

Do you need me to commit it?

Cheers,
Josh
