While accessing my Linux PC over ethernet from a Solaris x86 box via rsh and rcp commands, after 10 to 20 such commands the Linux host stops responding. Looking in /var/log/messages I see an entry like this: inetd[PID]: rsh/tcp server failing (looping), service terminated.
If the commands are successful, then this is a problem with the number of connections per second. Inetd turns off services that are spawning "too fast". The fix is to add a rate parameter in inetd.conf. Something like shell stream tcp nowait.256 root /usr/sbin/tcpd in.rshd should fix. Please reopen this bug if not.
