I've this strange problem.
My router crashes continuosly since few days.
Connecting to console port, I've seen that the error is:
*Jan 18 02:47:51.053: %BRI-1-NOMEMORY: Unit 0, no memory for ISDN L1 Q elements. L1 message not enqueued to L2.
*Jan 18 02:47:52.601: %SYS-3-CPUHOG: Task is running for (2004)msecs, more than (2000)msecs (58/1),process = ISDN.

So I thought that problem could be related to isdn, I disconnected vic-2bri module and router then worked properly.
I've reconfigured in another interface isdn bri configuration, and when I've "no shutdown" the new module, problem is reappeared.
It's sufficient to plug and unplug isdn bri cable to crash router or permit it to work properly.
I've made some research, and I've found that it could be a ios bug, so I've tried 3 different ios releases, but with no result (a 12.4T, a 15.1M and a 15.1T).
Router is a 2811.
Any suggestion will be great appreciated.
Thanks
Daniele
