No. It is a Solaris 9 and older documented behavior.
If you kill and restart inetd, be aware that any environment variables in your shell are inherited by a shell for an incoming telnet session. For example, if you have USER=root in your environment, a user who connects to your machine with telnet inherits USER=root.

Quote:
Or should I have restarted the service some other way?
If your goal was for inetd to reread its configuration, the documented way would have been to send SIGHUP to the inetd process, eg:
Code:
pkill -HUP inetd

Note that current Solaris releases (10, 11) no more use the same mechanism to restart this service so do not exhibit this issue.
