Subject: Re: [OMPI users] Question regarding SELF-checkpointing
From: Josh Hursey (jjhursey_at_[hidden])

That seems like a bug to me.

What version of Open MPI are you using? How have you setup the C/R
functionality (what MCA options do you have set, what command line
options are you using)? Can you send a small reproducing application
that we can test against?

That should help us focus in on the problem a bit.
