Hadd problem

[quote=“Wile E. Coyote”]Try to play with “user limits”:
[url]Upper limit of entries in one bin and in whole histogram
[url]No error when macro crashes
[url]File open limit?

Hi, thanks for the reply. I tried checking the limits and the output in the computer I am using is:

ulimit -n: unlimited
ulimit -s: 1024

I am not adding more than 1000 files and the memory is unlimited so I think that is not where the issue is.
