...e in R, and tail -f outfile, I got following:

Type 'q()' to quit R.

BACKGROUND:
While troubleshooting random, occasionally occurring, errors from
parallel::makePSOCKcluster("localhost", port = 11000);
Error in socketConnection("localhost", port = port, server = TRUE,
blocking = TRUE, :
cannot open the connection
I had another look at parallel:::newPSOCKnode(), which is used
internally to set up each background worker. It is designed to,
