It could be selinux. Processes started from init often run with a different
context than ones run by a user. If this is what is happening there should
be information about it in your logs.

You should probably look at any logs you have for the service to see what
is happening in any case. You can also use netstat or lsof to see if the
service is listening on the expected (any) ports. If so then there may
be a firewall issue, though it would be unusual for one to block different
ports based on what services have been started.
