I have a group-async interface defined with a 20 minute timeout (dialer idle-timeout 1200). All users are dropped when their "Time Since Activation" exceeds the idle-timeout even though the idle timer under "sh users" reports an idle time of 00:00:00. The idle-timeout is being treated as an absolute timeout. I am currently running IOS ver. 12.1.9 and mica modem code 2.7.2.0 I have tried several versions of IOS and they all yield the same result. My ISDN customers work fine. This identical config (below) does not produce this result on two other identical AS5300s.
interface Group-Async1
ip unnumbered FastEthernet0
encapsulation ppp

dialer in-band

Any ideas would be appreciated.
