Error in <TTreeCache::FillBuffer>: Inconsistency

beojan August 21, 2018, 1:16pm 1

Using RDataFrame, I get errors of the form:

Error in <TTreeCache::FillBuffer>: Inconsistency: fCurrentClusterStart = xxx fEntryCurrent = yyy fNextClusterStart = zzz but fCurrentEntry should not be in between the two

Is this something to worry about, and if so, how can it be fixed?

Which exact version of ROOT do you have?

6.14/03. Specifically, the dev4 LCG release (it’s the only one that is built with C++ 17 support).

The fix (commit 4d05469146) has been pushed to the v6-14-00-patch branch today (8/21/18) and I assume we appear shortly (days) in the build you are using.

The commit is in today’s build, but I still get the error.

Can you share a reproducer so we can fix your case too?

I can point you to the code: https://gitlab.cern.ch/OxfordATLASExotics/hh4b-resolved-reconstruction

It seems to be related to the multiple file support, since I don’t get this error if I run one file at a time.
