inetd ports hang when overused(?)

inetd ports hang when overused(?)

[Bruce Dobrin]

Hi,

(1.3.10,  win2k)
I am having a problem where I wrote an app that is called through inetd (on
port 1818) and when It is seeing a lot of traffic,  it will occasionally
become partially non- responsive.  All other ports are still fine but 1818
is hung (at least it seems to connect,  but not hook into the app).  If I
rlogin in and net stop and start inetd,  all is then fine.  Is this a known
issue?  I have noticed the same thing on other ports on earlier and the same
version of cygwin.  Specifically,  since I use rsh (rlogin) quite a bit,  I
have on occasionally seen  (example from another machine):

dobrin@THEODOLITE:/home/dobrin> rsh pronto
pronto% ls
pronto% pwd
pronto% exit
pronto% rlogin: connection closed.
dobrin@THEODOLITE:/home/dobrin>
dobrin@THEODOLITE:/home/dobrin> telnet pronto
Trying 172.18.5.130...
Connected to pronto.spimageworks.com.
Escape character is '^]'.

CYGWIN_NT-4.0 1.1.8(0.34/3/2) (pronto) (tty0)

login: dobrin
Password:
dobrin@PRONTO:/home/dobrin> net stop inetd
dobrin@PRONTO:/home/dobrin> net start inetd

....  and from then on it's fine

Any help appreciated.

Re: inetd ports hang when overused(?)

I haven't heard anything on this yet,  but I noticed an error message (in
the system log) which somewhat explains the situation,   But I'm not sure
what to do about it.
Cygwin Process Id = 0x668 : 1818/tcp server failing (looping), service
terminated.

I'm not sure I understand if inetd thinks it's  looping because it is under
continuous load,  or if it really is looping.  In either case I'm not sure I
know Inet well enough to know where to look..  Does anyone have any
suggestions?

Thanks,

Bruce Dobrin
