Rsession frequently crashes with render_snapshot() and plot_3d()

[richardtc]

The Rsession within RStudio server frequently crashes with render_snapshot() and plot_3d(). A point is reached where a file (v_mat matrix below) becomes too large to render when using render_snapshot and/or plot_3d. I guess this is related to the cache.

I have increased the resource limits in the Docker container (with installed RStudio Server) and on the host machine:

# rlimit_all()
# $cur
#      as    core     cpu    data   fsize memlock  nofile   nproc   stack 
#     Inf     Inf     Inf     Inf     Inf     Inf    4096     Inf 8388608 
# 
# $max
#      as    core     cpu    data   fsize memlock  nofile   nproc   stack 
#     Inf     Inf     Inf     Inf     Inf     Inf    4096     Inf     Inf

I run the Docker container with the --ulimit memlock=-1:-1 option.

Here is an error example error related to plot_3d:

   Error: rsession: cache resources exhausted `/tmp/RtmpivuAjx/file3e4e2c167.png' @ error/cache.c/OpenPixelCache/4095   

Alternatively, and typically, the session just crashes without any warning message with render_snapshot()

I'm running this code:

v_mat %>%
  sphere_shade(texture = "imhof2") %>%
  plot_3d(v_mat, zscale = 50, theta = 20, zoom = 0.65, fov = 0, phi = 35, windowsize = c(1000, 800))
  Sys.sleep(0.2)
  #render_snapshot()
  render_snapshot("FILENAME9.png", clear = TRUE)
