Thanks Josh.I've already check te prelink and is set to "no".I'm going to try with the trunk head, and then i'll let you know how it goes.
Best regards.Hugo Meyer2011/1/25 Joshua Hursey <firstname.lastname@example.org>Can you try with the current trunk head (r24296)?
I just committed a fix for the C/R functionality in which restarts were getting stuck. This will likely affect the migration functionality, but I have not had an opportunity to test just yet.
Another thing to check is that prelink is turned off on all of your machines.
Let me know if the problem persists, and I'll dig into a bit more.

> The checkpoint and restart works fine, but when i restore an application that has more than one process, this one is restored and executed until the last line before MPI_FINALIZE(), but the processes never finalize, i assume that they never call the MPI_FINALIZE(), but with one process ompi-checkpoint and ompi-restart work great.
