Hi Andy,

I updated the RPMs on the redirector in our production system to test the supervisors. Now, 4 out of 9 supervisors seems to be working and getting the necessary traffic. I do see though, some of them are going to status `suspend + nostage`. 

If the number of data servers (~250) are already handled by 3-4 supervisors, then do the extra supervisors go to `suspend + nostage` status by default ?

Here are the log from one of the working supervisors:

This is `cmsd.log` from another supervisor that isn't working:
