Question tcp port always closed in inetd

sco unix 5.0.x, several weeks ago, I add a telnet-like service in inetd.conf, it runs well for 100 network terminals.

But nowdays, the terminals can connect to server successfully after booting machine, but several hours later, can not connect. "netstat -p tcp -a" can NOT find the port in LISTENING state. If I "kill -1 pid-of-inetd" to refresh the inetd process, the port listens again and terminals can connect too. But hours later problem occurs again.

why and how to solve it?

Put the service entry in inetd.conf to begining of file?

NAME
in.lpd - BSD print protocol adaptor SYNOPSIS
/usr/lib/print/in.lpd DESCRIPTION
in.lpd implements the network listening service for the BSD print protocol specified in RFC 1179. The BSD print protocol provides a remote interface for systems to interact with a local spooling system. The protocol defines five standard requests from the client to the server: starting queue processing, transfering print jobs, retrieving terse status, retrieving verbose status, and canceling print jobs. in.lpd is started from inetd. See inetd(1M). inetd waits for connections on TCP port 515. Upon receipt of a connect request, in.lpd is started to service the connection. Once the request has been filled, in.lpd closes the connection and exits. EXIT STATUS
The following exit values are returned: 0 Successful completion. non-zero An error occurred. FILES
/etc/printers.conf System printer configuration database. printers.conf.byname NIS version of /etc/printers.conf. printers.org_dir NIS+ version of /etc/printers.conf. /usr/lib/print/bsd-adaptor/bsd_*.so* Spooler translation modules. ATTRIBUTES

The in.lpd service is managed by the service management facility, smf(5), under the service identifier: svc:/network/lp Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibil- ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config- uration information for this service. The service's status can be queried using the svcs(1) command. SunOS 5.10 5 Aug 2004 in.lpd(1M)
