Hi Andy, Thanks for the reply. We haven’t enabled blacklisting in our xrootd configuration, unless this is something enabled by default. Since we are relying on OSG packaging, I guess there is no easy fix on our side without waiting for the 4.1. Do you know if OSG provides a version with this patch applied ? -Tapas On Nov 20, 2014, at 5:42 PM, Andrew Hanushevsky <[log in to unmask]> wrote: > Hi Tapas, > > Yes, this is a known bug and will be corrected in 4.1. If you have enabled blacklisting (i.e. cms.blacklist directive) you should remove it.
