I encountered a problem about BLCR 0.8.0.
I run the NPB serial benchmarks on severl compute nodes of our cluster
and make checkpoints of them. The checkpoint process is OK and the
programs can be restarted from the context files from the same node
where it is checkpointed. But if I try to restart the program from
another node, which has the same architecture(x86_86), kernel(Linux
2.6.28-8.1.8-el5), and executable(shared NFS directory), the program
will report a segmentation fault after running successfully to the end:
...

I wonder if anybody else has run into this problem before.
