Popup error message

Popup error message shows up like this:

According to logs the intrinsic cause of it might be the disappearance of R temporary files (/tmp/RtmpHASH) cleaned by OS. For the sake of fast response the shiny app is configured to never finish by timeout (to save on initial loading), so does the corresponding R-session. R-session eventually suffers from loosing temporary files it depends on.

The possible solution is to move temporary files to permanent disk space.

I believe this is considered fixed but not sure if a change was made to code/config that needs to be part of the repo?

We wait to see if it reoccurs. No, the fix is rather a detail of shiny-server installation/implementation.
