URGENT: strange host name mismatch

After 32 active telnets, the next one gets no login: prompt.
As soon as somebody else logs out, the login comes again.

Is there any limitation in telnet or in.telnetd?
/etc/xinet.d/telnet has none.

This is Suse 8.2

/var/log/messages does not help. There are entries like
Nov 18 10:45:32 curlinux xinetd[8066]: warning: /etc/hosts.allow, line 48:
host name mismatch: ::ffff:192.168.1.127 != ::ffff:192.168.1.127X
(::ffff:192.168.1.127)

but they seem not to be related. 192.168.1.127 is not yet in /etc/hosts,
but at the point of failure it is already logged in several times.

BTW I know we should use ssh but that would mean to install dozens of new
terminal emulators on the client pc's

Well, I just found the instances parameter in xinetd.conf.
Sorry for the noise.

Do you have an "instances" entry in /etc/xinetd.conf?
