When using Pluto for long running Pluto notebooks, after some days, I am running into the following

Worker 6 terminated.
UNHANDLED TASK ERROR: EOFError: read end of file

The best help I could find so far is from this stackoverflow which mentions and out of memory as on potential source of this error.

I indeed was able to fix a couple of memory leaks on my side but think that there is no memory now any longer (I am plotting memory consumption and it looks constant).

Hence I am looking for other potential sources of this error, but couldn’t find any so far. (Apparently you get it too if you interrupt(2) a worker 2, but this will also output more loggings about which error was not handled - I really only have the above output, nothing more)
