Hi Gene,Thanks for debugging this. I saw in one of your slides talking about handling of this Linux security measure of address space randomization where special measures were taken at restart time to grow stack to include old stack. Is this expectation of 1MB stack size accommodation broken here ? Also turning off randomization on per process basic would not be possible in our system which is too complex involving multiple processes coming from different teams here
@Kapil: I am attaching the map file with this, also mentioning the error for reference. I guess you are correct, restart time is trying to unmap special memory segment which comes at last below the stack

P.S., one way to turn off randomization on a per process basis is the -R flag of 'setarch'. - Gene ----- Original Message ----- From: Gene Cooperman <g...@ccs.neu.edu> To: Ankit Garg <ankit_g...@mentor.com> Cc: Gene Cooperman <g...@ccs.neu.edu>, dmtcp-forum@lists.sourceforge.net Sent: Sun, 12 Apr 2015 00:02:49 -0400 (EDT) Subject: Re: [Dmtcp-forum] Trying to use mutl-arch support having mixture of 64/32 bit executable Hi Ankit, I can report some progress. I was able to reproduce the bug on a Centos 6 computer. I would guess that the bug appears for Red Hat versions 5 and 6, and the derived distros. In addition, the DMTCP bug appears to be related to address space randomization. I turned off address space randomization: sudo bash -c ' echo 0 > /proc/sys/kernel/randomize_va_space' and the bug went away. Naturally, DMTCP is supposed to also work correctly when address space randomization is turned on. I'll continue to work on that case. In the meantime, you can use DMTCP in your app, if you're in a possition to turn off the randomization. There are also methods to turn off randomization on a per-process basis, but that would be painful if you have to do it for each process.
