error in parallel:::sendMaster
Hi Andreas,
the error is reported when some child process cannot send results to the
master process, which originates from an error returned by write() -
when write() returns -1 or 0. The logic around the writing has not
changed since R 3.5.2. It should not be related to the printing in the
child, only to returning the value. The problem may be originating from
the execution environment,
