'DT table notification pops up frequently

I have a shiny application where there is a DT table. The app is all fine but most of the time, i see this notification popping up. Not sure what it is. Sometimes, it does not. Can anyone help me?

Using client side processing in DT::renderDataTable helped solve this issue for me https://rstudio.github.io/DT/server.html

DT::renderDataTable(iris, server = FALSE)
