sparkr databricks error: too many open devices

Question

I was using simple data manipulation using sparkr on Databricks. The code was working just fine a minute ago and suddenly I started getting the following error:

Error in png(fileName, width = plotWidth, height = plotHeight, pointsize = plotPointSize, : too many open devices

This happens even if I use, for example:

mtcars %>% select(mpg)

I was not making any plots. What could the solution be?

I believe this can be done without restarting the cluster. Just Clear State and Results and Run them all again and you will be good to go.

Ok. Thanks for the suggestion! – Geet Sep 21 '18 at 17:34

Thank you. `Clear States` was enough for me, I did not need to `Clear Results`, too. – Jens H Nov 07 '19 at 14:01

I am experiencing the same problem. The only solution seems to be to restart the cluster you're working on.
