Re: [Condor-users] How to make condor suspend jobs partially

[Andy Anderson <aanderson@xxxxxxxxxxx>]

I assume that Condor is sending the SIGSTOP to the entire process  
group, which includes your original job and any children it forks. I  
don't think you can remove a child from the process group (but I'm not  
an expert).

Is it essential that you keep the same kerberos ticket, as opposed to  
authenticating again and using a new ticket?
