[Condor-users] Problem with Condor standalone library

["Tanzima Zerin Islam" <tz.islam@xxxxxxxxx>]

Hi,
 I have been trying to checkpoint one of my applications using condor's standalone library. What I am doing is:

condor_compile gcc myapp.c -o myapp
./myapp

then according to condor's manual, sending ctrl-Z signal should take a checkpoint myapp.ckpt and stop.

But the problem is, when I send ctrl-Z signal, it takes creates a file
- myapp.ckpt.tmp and prints - Killed in the standard output.

The output is:
Condor: Notice: Will checkpoint to ./myapp.ckpt
Condor: Notice: Remote system calls disabled.
1
2
3
4
5
Killed  <-- at this point I sent CTRL-Z


then, when I am trying to restart the process by writing -

./myapp -_condor_restart myapp.ckpt.tmp

it says something like : 

Condor: Notice: Will restart from myapp.ckpt.tmp
Killed

----
Could
you please put some light on what I am doing wrong here? And another
question is how to send SIGUSR2 signal , I mean CTRL-?
I will appreciate any help. Thank you.
