@bockjoo - does the problem go away if you turn off asynchronous IO? That is, try adding: ``` xrootd.async off ``` Has this been ongoing for awhile or is it something new? I suspect it's probably due to the fact that `XrdLcmaps` links against Globus to do the proxy verification and that is somewhere causing Globus to try and take over signal handlers. Nothing else I know of besides Globus would touch that from a plug-in point-of-view. -- You are receiving this because you commented.
