Assume that you use an RX function such as rxReadXdf to read a data buffer from a named pipe, but the operation is interrupted—for example, by the rprof function. In this situation, the read operation fails. Additionally, errors that resemble the following are triggered:
Error indoTryCatch(return(expr), name, parentenv, handler) :
message header:expected 80000703 got Failed to allocate4813005498972314624 bytes of memory.Error in doTryCatch(return(expr), name,parentenv, handler) : Failed to allocate4813005498972314624 bytes of memory.

To resolve this issue, follow these steps to apply the fix:
Put the required files in a temp directory, where the user who applies the patch has read/write permissions.
Open a command line with elevated permissions. For example, in Linux, launch a terminal, and then use sudo to execute commands.
Uninstall the current RevoScaleR package. In Linux, run the following command: sudo R CMD REMOVE "RevoScaleR"
Stop the BxlServer process and all other R processes. In Linux, either use "kill" or top to stop BxlServer and R.
Install the new package from the RevoScaleR archive. In Linux, run the command: sudo R CMD INSTALL --no-test-load <path/to/dir> /RevoScaleR_8.0.X.tar.gz
Copy the RxLink Library file to your RevoScaleR directory. In Linux, run the command: sudo cp <path/to/dir>/libRxLink.so.2 \ <path/to/R_dir>/library/RevoScaleR/rxLibs/x64/ Note On a standard install, the <path/to/R_dir> placeholder resembles the following: /usr/lib64/MRO-for-MRS-8.0.X/R-3.2.2/lib64/R
Launch R, and then import a Data Frame to validate that the patch is applied.
