Dear Roofit experts,
I am running a macro with RooFit v3.17 that performs an ML fit over data that has been separated into 40 bins. It runs fine until eventually I read on the output
[#1] INFO:Eval -- RooAbsTestStatistic::initMPMode: starting remote server process #8
pipe: Too many open files
and soon after
RooRealMPFE::evaluate(nll_mdlPdf_HISingleMuon_HP16Feb.root_ea868e00_MPFE6) ERROR: unexpected message from server process: 1897398272
Any help on why this is happening and how to fix it? Thanks.
