I observe that a significant fraction of the help requests, both here and in the old support.RStudio.com forum, have to do with fully or partially unresponsive RStudio sessions. Some hang occasionally, some indefinitely; sometimes it is the whole system, other times (as in my recent and still unanswered help request below) it is just one pane or function.

I imaging the RStudio folks have by now troubleshooted (troubleshot?) a large enough number of these cases to have accumulated some general wisdom about this – things to try, diagnostic techniques, ways to figure out if the problem is with R or RStudio, and so forth. Is there is an RStudio-level equivalent of R’s sessionInfo?

Maybe it would even be worth a pinned thread? What do you think?
