You're running stunnel and bash (and probably SysVinit and xinetd), and
you point the bloat finger at one little runsv process?

If you want to start a new shell less frequently, do:

#!/bin/ash
while true
do
 runsvctrl alarm /var/service/socklog/log
 sleep <seconds>
done

If you want a small solution, write a small program which trickles "a" 
characters into the control fifo for socklog/log, then supervise it.
