  • I have not seen this particular error before, but the error seems to indicate that you may have corrupted your current R session. I would try running the rxGetInfo command from a new R session - does that work?

  • Nope, restarting the sessions didn't help.

    The error appears in VSTS and Rstudio. In RStudio is switched a couple of times between the R versions of Microsoft and the open R source. Perhaps I screwed something up there...

    I also tried to install RevoScaleR in the R open version, but that didn't succeed either.

  • The error message seems to indicate a problem with the BxlServer connection that is part of RevoScaleR, however I am not certain what caused the crash in your instance.

    It may be that you have a corrupt XDF file or a corrupt installation.

    I would first try rxGetInfo() on one of the built-in XDF files that come with Microsoft R Server:

    Does the following work?

    rxGetInfo("C:/Program Files/Microsoft/ML Server/R_SERVER/library/RevoScaleR/SampleData/AirlineDemoSmall.xdf", getVarInfo = TRUE, numRows = 10)

    If no, you have probably corrupted your install and should try reinstalling Microsoft R Server.

    If it works, your XDF file may be corrupt.
