Pluto disconnects the running process due to ECONNRESET error

[eladfisher]

Hi, my notebook crashes when running heavy computation, after several hours, it happened several times already, but it isn't consistent, and i could not reliably reproduce the error.

the stack trace is (with the warnings that printed with the crash itself):

unfortunately, i can't reproduce or give a minimal working example, so i don't have much to add to the stack trace, i tried to update Pluto to v0.19.36 from # v0.19.32, but it didn't fix the problem, also the same notebook worked before, so i don't think it something that i did.

The first two warnings are unrelated.

The final error message just says that the notebook process crashed. This could be because it ran out of memory. Did you also run the same computation outside of Pluto? You could try to run include("my_notebook_file.jl") in a REPL?
