[Condor-users] unable to restart from a "checkpointed" process

[Adrian Tang <Adrian.Tang@xxxxxxx>]

Hi,

I have a simple test app try out Condor's stand alone checkpoint and 
restart.
However, I am unable to restart from "checkpointed" file. See attached 
for run log.
Here's the scenario:

1.  start program that prints a count every second.
2. checkpoint the process (send SIGSTOP)
3. restart the process
4. checkpoint the process (send SIGSTOP)
5. restart the process

Expected Result:
process starts counting again

Actual Result:
Killed

I have tried deleting the checkpoint file after step 3 and before 
executing step 4 and
get the same result.

Thanks for any help,

Adrian
