When Condor-G detects that the proxy has been refreshed, it invokes  
Globus GRAM's proxy refresh call to forward the updated proxy to the  
job. The Globus JobManager receives the refreshed proxy and replaces  
the old proxy for the job.

The JobManager writes the new proxy to disk and then calls a perl  
script that can be customized in case the local scheduler needs to  
take further action to get the proxy to the job. The perl script does  
nothing normally, but you should check if yours is doing something  
weird. Look in $GL/lib/perl/Globus/GRAM/JobManager.pm and $GL/lib/ 
perl/Globus/GRAM/JobManager/fork.pm for a subroutine called  
proxy_update.
