Dear All,
         I have installed BLCR 0.8.1 and OPENMPI 1.3 on a linux platform. However, when i tried checkpoiting an application, it hangs forever just before ending.

A chekcpoint file is generated. However, when i try restarting it, i get the following error:

raj_at_sun06:~$ ompi-restart ompi_global_snapshot_22390.ckpt
