rserver can crash when proxying traffic to a websocket #2061
Steps to reproduce the problem
Describe the problem in detail
Many customers are seeing RStudio Server crashes with the following log entry:
We were able to collect the following crash log from one such customer:
This trace suggests that an error while closing the websocket that rserver is proxying to is crashing the rserver process; the customer supplying has noted that these crashes seem to correlate with running Shiny applications inside RStudio Server, but it doesn't happen every time (or even most the time).
However, it bears investigating as we see a lot of rserver segfaults in customer logs and while it's possible that they're all caused by different things it's more likely that there are one or two issues responsible for the majority of the crashes, of which this may possible be one.
See internal ticket 24819 for an example.
