NanoPlot crashed - OSError: [Errno 24]

[AndiBagi]

Hi,

Thank you for your work invested in NanoPlot!

I have been using it successfully so far - but since I reinstalled it using pip, I am getting the below error message after nanoplot crashes. The input summary file is rather large (~6 GB). I am using a linux operative system - attached you can see the log file.

Thank you for any comments & hints in advance! Andrea

I haven't see this error before, was it only a temporary thing or could you replicate this on a later day?

I got the same error on two consecutive days - haven't tried more afterwards.

Doing ulimit -n 2048 was a quick fix for me!
