Hi all, For the last few days I have been trying to produce some ntuples for my analysis, using miniAOD files located here: root://cms-xrd-global.cern.ch//store/mc/RunIIFall17MiniAOD/.... When I run my configuration file interactively everything works smoothly and I get the expected ntuples. However, when I am submitting my jobs at the batch system of lxplus my jobs exit unsuccessfully with the following message in the STDOUT file: ==== running ==== Reading phedex query from cache: 846 samples, 0.6 hours old Error in <TNetXNGFile::Open>: [FATAL] Redirect limit has been reached loading FWLite.

I am ssh-ed to an lxplus machine (connected from Greece) and using python 6.10/09 in CMSSW_9_4_11. I would really appreciate any help or insight on how to overcome this error and continue the tuple production on the batch system. Also, it is not very clear to me why I do not get the same error message when I run interactively. Thanks a lot in advance, Ioanna ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
