running into a weird issue. we have a 2811 we use to dial into oob modems we have on other gear. we telnet into the 2811 or port 7001 which is linked to 5 modems/ttys. often after we disconnect the tty still shows in use. you cannot "clear" the line. eventually all ttys are stuck in use and we need to reboot the box to clear it. we have current code on it. any thoughts? as far as configs this is what we have

line 1/0 1/5

session-timeout 15

exec-timeout 5 0


login authentication local_auth

modem DTR-active

rotary 1

transport preferred telnet

transport input telnet

transport output telnet

escape-character NONE

How are you terminating the calls? Are you issueing a disconnect command on the 2811?

Obviously that is preferred however I am sure some users are simply closing the xterm or ssh window. However even if that was the case shouldnt I at the very least be able to clear the stuck lines with the "clear line" command? And beyond that I would think the cisco would be able to determine that the controlling telnet session has gone away. Is that unreasonable?
