App logs show out of memory message, metrics show less than 300MB memory usage, but instance size set at 1GB?

shiny shinyapps.io
1

Hello, my problem is as it says in the title, I'm wondering if anyone knows what is going on?

I have used profvis to track memory usage of this app, and it also did not show so much memory usage (at least in difference between memory allocation and deallocation).

Thanks in advance for any help!

Shinyapps.io memory usage metrics:

screen1
screen11061×348 21.9 KB

Instance size:

screen2
screen2785×129 8.22 KB

Profvis results:

screen3
screen31110×300 12.9 KB

(The first negative memory value is -16916.8)

I think you need to look at the detail of the profvis info that is aggregated into the first entry. a de-allocation of 1600mb (and a 1700mb allocation shown on the right of that) , implies you will have likely blown through a 1Gb instance.
