I have an application which I want to access via xinetd in single-threaded mode (option wait=yes). However, any attempt to connect to the port where xinetd is listening fails, and the xinetd log shows message "Deactivating service foo due to excessive incoming connections." If I change the option "wait" to "no", for multi-threaded mode, everything works. Reproducible: Always Steps to Reproduce: 1. Create a single threaded xinetd service, e.g. the following. I have used aspell as an example, but any application that reads stdin and writes to stdout will do. service ispell { disable = no flags = NORETRY NOLIBWRAP protocol = tcp socket_type = stream wait = yes user = root instances = 1 server = /usr/bin/aspell server_args = -a bind = localhost log_on_success += HOST log_type = SYSLOG daemon debug } 2. Add an entry in /etc/services for the service you just created, e.g.: ispell 8091/tcp 3. Restart xinetd and try to telnet to that port: telnet localhost ispell Actual Results: telnet localhost ispell Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. Here's the relevant contents of /var/log/syslog: Sep 23 14:43:43 pequod xinetd[6171]: xinetd Version 2.3.12 started with libwrap loadavg options compiled in.

how about 2.3.13 ?
any luck with 2.3.13 ?
Reproduced issue on sparc 2.3.13
ok ...
i tried talking to upstream but got no response ... best to try contacting them since you guys have the systems with which to reproduce :/
