Hi all,
Apologies for repeating myself, as I've submitted my issue here
https://github.com/dmtcp/dmtcp/issues/392 ... but perhaps I should have
posted here before doing so?
I'm getting overlapping address errors on my attempts to use dmtcp (2.4.4
or 2.5.0-rc2) on Ubuntu 15.04, 15.10, or 16.04. The second restart
produces something like the following:
[13182] mtcp_restart.c:682 unmap_memory_areas_and_restore_vdso:
*** MTCP Error: Overlapping addresses for older and newer
vDSO/vvar sections.
vdsoStart: 0x7fffefffd000 vdsoEnd: 0x7fffeffff000 vvarStart:
0x7fffefffb000 vvarEnd: 0x7fffefffd000
rinfo:vdsoStart: 0x7fffefffa000 vdsoEnd: 0x7fffefffc000 vvarStart:
0x7fffefff8000 vvarEnd: 0x7fffefffa000
Ubuntu 12.04 seems to work OK (maybe due to no [vvar]?)
To reproduce:
With `dmtcp_coordinator -p 12345 -i 15` running...
$ dmtcp_launch -p 12345 --no-gzip bash do_stuff.sh
---- CTRL-C after a checkpoint or two
$ ./dmtcp_restart_script.sh
---- CTRL-C after a checkpoint or two
$ ./dmtcp_restart_script.sh
[13182] mtcp_restart.c:682 unmap_memory_areas_and_restore_vdso:
*** MTCP Error: Overlapping addresses for older and newer

vdsoStart: 0x7fffefffd000 vdsoEnd: 0x7fffeffff000 vvarStart:

rinfo:vdsoStart: 0x7fffefffa000 vdsoEnd: 0x7fffefffc000 vvarStart:
0x7fffefff8000 vvarEnd: 0x7fffefffa000
do_stuff.sh
---------------
#!/bin/bash
x=0
while [ 1 ]; do
echo $x
sleep 10
x=$(( x + 1 ))
done
Any help would be much appreciated.
Thanks,
Brian
