1. Change this to use strace:

startproc -p /var/run/ipservice/ipservice.pid -W /var/run/ipservice/ipservice.pid  strace -f -o /tmp/start.log /usr/local/bin/ipservice -r -D -s /usr/local/bin/ipservice.conf

in /tmp/start.log you'll then see what the process is doing.

2. Try starting the process manually
strace -f -o /tmp/start-man.log /usr/local/bin/ipservice -r -D -s /usr/local/bin/ipservice.conf

and see if there is a difference.
