Following error appears in log /project2/lgrandi/xenon1t/cax/6340_v6.4.2/6340_v6.4.2_24185396.log:

cax_v5.0.9 - 2017-02-21 16:07:37,716 [ERROR] Failed filling branch:tree.events, nbytes=-1, entry=18242
 This error is symptomatic of a Tree created as a memory-resident Tree
 Instead of doing:
    TTree *T = new TTree(...)
    TFile *f = new TFile(...)
 you should do:
    TFile *f = new TFile(...)
    TTree *T = new TTree(...)

but then still finishes successfully, so cax thinks it's transferred successfully, but actually the file is corrupt.

Maybe some issue hitting compute node memory limitation...
