Bug still exist in this case:
daniele@build-jessie-amd64:~$ grep "^iperf" iperf-daemon.sh
iperf3 -s </dev/null >/dev/null 2>&1 &
daniele@build-jessie-amd64:~$

daniele@build-jessie-amd64:~$ ./replicator.sh
    env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin, log_output, log_output, maxseq=150, iolog_mode=750, iolog_dir=/var/log/sudo-io/%{user}, !requiretty
/usr/bin/iperf3
running KO test
no sleep
iperf3 KO
iperf3: no process found
running OK test
sleeping 3s
iperf3 KO
iperf3: no process found
daniele@build-jessie-amd64:~$

Bug does not exist in this case:
daniele@build-jessie-amd64:~$ grep "^iperf" iperf-daemon.sh
iperf3 -s -D
daniele@build-jessie-amd64:~$

daniele@build-jessie-amd64:~$ ./replicator.sh
    env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin, log_output, log_output, maxseq=150, iolog_mode=750, iolog_dir=/var/log/sudo-io/%{user}, !requiretty
/usr/bin/iperf3
running KO test
no sleep
3624
iperf3 OK
running OK test
sleeping 3s
3633
iperf3 OK
daniele@build-jessie-amd64:~$

Is this changing your analysis?

Thanks,
Daniele
