[Dmtcp-forum] anyway to attach a restarted process?

[Nausca <na...@ca...>]

Hi,
after checkpoint, I have try to attach a restarted process by gdb,
but I get such message that indicate no symble table is loaded.
any idea how can we use gdb to debug a restart process?

Attaching to process 2454
/proc/2454/exe: No such file or directory.
A program is being debugged already.  Kill it? (y or n) n
Program not killed.
(gdb) n
Cannot find bounds of current function
(gdb) finish
No selected frame.
(gdb) break main.c:120
No symbol table is loaded.  Use the "file" command.
(gdb) file /home/nausca/a.out
A program is being debugged already.  Kill it? (y or n) n
Program not killed.

thanks.
nausca.
