Rmarkdown fails rendering large documents from many child files

[JasonCEC]

Hey rstudio team,

I'm getting:

Quitting from lines NA-xx (./xxxxxx.Rmd) 
Error in file(file, ifelse(append, "a", "w")) : 
  all connections are in use

When rendering files about ~100 pages long or so;
is there an easy solution like closing intermediary connections in the code blocks,
or something else I can do to fix this?

Cheers!

@JasonCEC how many lines approximately is the input file? Also, were there a lot of code chunks? Finally, could you post your session info?

Hi,

cc @larual

I think I have a related issue with the rendering procedure taking place in my tool, reported by some users:
sigven/oncoEnrichR#4

Basically, HTML rendering crashes at times (have not been able to understand what exactly triggers the error)

For my tool, I have an "index" document that includes a number of child documents, that each are being included pending on various conditions:
https://github.com/sigven/oncoEnrichR/blob/master/inst/templates/index.Rmd

If there is any way to resolve this connection issue, I would be very grateful!

thanks,
Sigve
