Hello,
When I attach gdb to a process, as soon as a I enter 'continue', I see a SIGSTOP message. 


Reading symbols from /usr/local/lib64/libstdc++.so.6...done.
Loaded symbols for /usr/local/lib64/libstdc++.so.6
0x00007f5cc53d8b7b in raise () from /lib/x86_64-linux-gnu/libpthread.so.0
(gdb) c
Continuing.

Program received signal SIGSTOP, Stopped (signal).
0x00007f5cc53d8b7b in raise () from /lib/x86_64-linux-gnu/libpthread.so.0
(gdb)

The strange thins is that the program (which is running on another terminal) has no progress.
What does that mean? Thanks

 
Regards,
Mahmood
