It happens around 500 or so connections. I

I think you are spot on David. xinetd has a default of 60 instances per
daemon active at one time. This is configurable in xinetd.conf or in the
individual config files for each daemon. The 7.2 default, again, is 60
per daemon and the default rsh config file does not override that
default.
