_______________________________________________________
Details:
The message comes if the parallelism of xargs is
increased/decreased several times in a short time.
Test case (OpenSuSE 11.4, ext4, xargs from git):
mkdir /tmp/test
cd /tmp/test
dd if=/dev/zero of=1M bs=1M count=1
seq 4000 | ~/git/findutils/inst/bin/xargs -P 2 -n 1 cp 1M & pid=$!
sleep 1
while kill -USR2 $pid ; do sleep .1 ; done
The following error message appears about every 2-5 seconds,
in total 11x out of the 552 times SIGUSR2 has been sent to xargs:
/home/berny/git/findutils/inst/bin/xargs: errno-buffer read \
failed in xargs_do_exec (this is probably a bug, please report \
it): Interrupted system call
