I usually do not use restart (as stop/start sequence), because graceful
reconfiguration using -HUP or online binary upgrade are enough.

On fresh servers I start nginx using:
/usr/local/etc/rc.d/ start
This is always run via ssh and I never saw any ssh issues.
Just tried to start using
ssh root at host /usr/local/etc/rc.d/ start
without any problems.

The problem is probably in "service" utility. What is it ?
