Hi folks - I've ran into a snag, uploading large SAS data sets into my working environment using the read_sas() function from the haven package. A month ago, this worked relatively quickly, and possibly, after computer updates and updating both R/RStudio, the problem was born; uploading 2-15 GB data sets were taking 15 minutes to a few hours. From what I observe in the environment pane, is that the data uploads most of the way, and then inches along, as indicated by the checkmarked "Show Current Memory Usage".
I was originally using R v4.5.2 but reverted back to v4.5.1. I was also using the latest RStudio version 2026.01 but went back to 2025.09.
I've also tried using the most up-to-date version of haven, installing it from github/devtools.
When uploading data that is larger than 2GB, I observe in the environment tab that it uploads a large share of the data, but then inches its way to the finish line. I also have a 15.3 GB data set that was previously uploaded without issue. In the upper right corner, I've also observed a green circle, by the stop sign, that says "session suspend timeout paused a child process is running waiting for event console_input". I'm sensing that I need to look into the diagnostics but I wouldn't know what to look for.
Any thoughts folks?
