Hi Calvin, This has nothing to do with the kernel/CPU architecture. I personally run Linux-4.5 and it works. The issue is that DMTCP is getting into an infinite recursion which results in a segfault when it runs out of memory.
What DMTCP version are you using? If you are using a fairly recent version from the 2.5 branch there's a known issue. You will need the following patch: https://github.com/dmtcp/dmtcp/pull/378. (This will soon be pushed upstream; the corresponding fix for the 3.0 branch has already been upstreamed.)
