Channel states on a Cisco 7206 using the show isdn service command.

When I run the show isdn service command on my Cisco 7206, a large number of the channel states are always stuck in state = 4 (Restart).

router>sh isdn service

Gradually, over a period of time most of these channel states read as 4 (Restart), and do not transition to 2 (Busy) or 0 (Idle). The only way I am able to return all the channels back to a state of 0 (Idle), is to shut/no shut the E1 controller.

What could be causing this? Is the an IOS bug? I am using the following IOS version:

router>sh ver

Cisco Internetwork Operating System Software

IOS (tm) 7200 Software (C7200-JS-M), Version 12.1(2)T, RELEASE SOFTWARE (fc1)

This Looks like a bug in Cisco IOS. Check the bug ID CSCds52964 in bug toolkit.
