> [Logger,ERROR] [mlogger.cxx:3358:root_write,ERROR] Cannot write system event into ROOT file, event_id 0xffff8000

Hi, Andreas, please open a bug report for this problem on bitbucket, there is now at least 2 bugs against
the ROOT writer (some events are written in duplicate sometimes), and I hope to fix this next time i review
the mlogger (RSN!). Biggest problem is that I do not use the ROOT output myself, so I have no way
to know if ROOT files produced by mlogger are correct or make sense. (without setting up some kind
of test environment with a ROOT file reader.

Thank you for reporting this problem here, so more people know about it.

If somebody has a patch to fix this, please send it in!

K.O.
