Error reading file in /tmp

shiny

I have a long-running shiny app (not managed by shiny server), and it crashed with this error:

Warning in file(open = "w+") :
  cannot open file '/tmp/Rtmp6S6RW8/Rf56d0258d0a68': No such file or directory
Warning: Error in file: cannot open the connection

It is running on an EC2 instance with nothing else on it, so I don't think the /tmp folder is being cleaned in any way (besides, it contains files from last August).
Any idea whay might be happening?
