R session disconnected

R code
1

Hello,

I keep getting this message when I try to run R code that pulls data from an SQL server via VPN.

Does anyone have a list of possible reasons this could be occurring (without seeing my code)? Thank you-Drew

Hey Drew,

That message is usually not caused by your SQL code directly. It means your RStudio Server / Posit Workbench session got disconnected, and the browser thinks another connection took over or that is was restarted.

I cant really tell what caused this, but these are some possible reasons:

  • Browser-to-Workbench connection dropped (read more here: Troubleshooting RStudio IDE Connection Errors – Posit Troubleshooting )
  • Session process crashed or was killed: the underlying rsession may have exited because of an R crash, native-code crash from a package, out-of-memory kill, or host/container restart
  • Resource pressure on the host: low RAM, CPU saturation, disk pressure, or container/node termination can make sessions disappear or become unreachable
  • Authentication expiry
  • Multiple tabs / stale browser state

Any other information could help us determine the root cause!

Let me know,
