Segmentation violation

[Shibi]

Hi,

I was wondering if I could get some help in finding out why the errors below are occuring. Analysis_Ex is being run on 2 million events, and around 1M events it crashes. Could really use some advice for this problem. Thanks.

Hi,

It looks more like a root-related issue. Could you just check how much of your memory is used by delphes at the time of the crash ?
