Re: [Condor-users] Problem with Condor standalone library

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

Hi Daniel,
 Thank you for your suggestion. Well, I just tried now with setting arch, but still it takes myapp.ckpt.tmp. So that means 
the checkpoint is not successful. The kind of application I am running is a very simple helloworld application. that waits for sometime and
prints a value. so, type of application is not the problem. Moreover, I have also tried to send USR2 from another terminal, 
but still the chekcpoint taken is a .tmp file. What do you think could be causing this problem?

Try running it this way:

setarch i386 -R ./myapp

The fact that the checkpoint file has ".tmp" at the end is a sign that
the checkpoint was not successful.  If the previous suggestion worked,
you will also want to restart like this:

setarch i386 -R ./myapp -_condor_restart myapp.ckpt

As far as I know, you need to "kill -USR2 <pid>" from another terminal.
