No TCP server started

[Pierrick M Hanlet via Tech-talk <tech-talk@aps.anl.gov>]

Hi,
I've several soft IOCs happily running 7.0.3 on linux-x86_64 on different ports.  However,
I have a new one which is connected to a ethernet<->serial converter which runs
without issue from a terminal, but fails with "No TCP server started" when started
from procServ.  A similar message was reported to core-talk by Heinz Junkes when
using 3.16.0.1-DEV-fhi.

This has nothing to do with my databases, as I have them commented out:

My startup command is:
epics:~/epicsDEV/Config/ProcLauncher> procServ -i ^D^C --killsig 15 --logfile /home/epics/epicsDEV/ioc_logs/Keithley2700_2019_10_29__11_59_38.log --name Keithley2700 --pidfile /home/epics/.PROCSERV_CMD_1572368378214534208 --quiet 7718 /home/epics/epicsDEV/iocTops/Multimeter/iocBoot/iocKeithley2700/st.cmd

And the resulting log file has:
@@@ Restarting child "Keithley2700"
@@@    (as /home/epics/epicsDEV/iocTops/Multimeter/iocBoot/iocKeithley2700/st.cmd)
@@@ The PID of new child "Keithley2700" is: 7855

Any ideas?  If helpful, the device is a Lantronix UDS2100 serial-to-ethernet converter; though I
don't know if that matters.
Thanks,
Pierrick
