[R] Regarding Issue Running Parallel Computing on Linux RHEL version 8

[Huseni, Sadamhusen]

Hi Team,

I am writing to bring to your attention an issue we have encountered following the recent update of our Linux server from RHEL 7 to RHEL 8. We have an R script designed to create demand forecasts utilizing parallel computing on the Linux server.

Before the version update, the script executed successfully within approximately two hours. However, since updating to RHEL 8, the script has been hanging and not completing its execution even after running for 17 hours.

Here are some details about the problem:

Script Purpose: Demand forecasting using parallel computing.
Previous Environment: Linux server version RHEL 7.
Current Environment: Linux server version RHEL 8.
Issue Observed: The script hangs and does not complete execution post-update. Previously, it took around two hours; now it runs for over 17 hours without finishing.
We need assistance in diagnosing and resolving this issue as soon as possible. I will share detailed logs and any other necessary information upon request.

List of libraries used as below.
  library(foreach)
  library(parallel)
  library(parallelly)
  library(forecast)
  library(tseries)
  library(prophet)
  library(lubridate)
  library(tis)
  library(tsoutliers)


Thanks,
Sadam
