# produce input slowly to parallel so that it will reap a process
|
|
# while blocking in read()
|
|
# Having found the solution it is suddenly very easy to reproduce the
|
|
# problem - even on other hardware:
|
|
#
|
|
# perl -e '@x=1 .. 17000; for(1..30) { print "@x\n"}' | pv -qL 200000
|
|
# |parallel -j2 --pipe --keeporder --block 150000 cat | md5sum
|
|
#
|
|
# This gives different md5sums for each run.
|
|
#
|
|
# The problem is that read(STDIN) is being interrupted by a dead
|
|
# child. The chance of this happening is very small if there are few
|
|
# children dying or read(STDIN) never has to wait for data.
|
|
#
|
|
# The test above forces data to arrive slowly (using pv) which causes
|
|
# read(STDIN) to take a long time - thus being interrupted by a dead
|
|
# child.
