[Dmtcp-forum] Can't checkpoint a "gdb attach" process when started using dmtcp_restart

[Phan, L. H (3443) <Lin...@jp...>]

Hi,

  I can't checkpoint a "gdb attach" process when started using dmtcp_restart.  The dmtcp_restarted process just hangs when I type "c" in the dmtcp_coordinator window (if I've attached to that dmtcp_restarted process with gdb; if I've not attached with gdb, the "c" commands works fine).  I've noticed that QUICK-START mentioned to use "mtcp_restart" and not "dmtcp_restart" when attaching using gdb, but when I do that, I get this error:

$ mtcp_restart myprog.dmtcp
[0] mtcp_restart.c:219 main:
  'myprog.dmtcp' is 'DMTCP_CHECKP', but this restore is 'MTCP64-V1.0' (fd=4)
$

Any ideas?

Thank you,

Linh
