We've seen that here at NCSA as well.  The workaround is to CTRL-C the 
AGServiceManager.py process before the proxy expires.  We do this after 
each AG meeting, similar to what we did with arm-eventlistener and 
vrm-eventlistener way back in the AG1 days... ;-)

There are Bugs #896 and #793 reported on this issue.
