[c-nsp] Cisco 3700 dialin Problem after crash

[Florian Prester]

Hi,

i have a Cisco 3700 with IOS 12.3(5.b).
I tried to configure it to act as an dialin-server for ISDN and intern 
analog modems.

First it seemed to work, but after one day the router raised a software 
crash:

%ALIGN-1-FATAL: Corrupted program counter
 pc=0x0, ra=0x608B29B0, sp=0x61E96F78

%ALIGN-1-FATAL: Corrupted program counter
 pc=0x0, ra=0x608B29B0, sp=0x61E96F78


Unexpected exception, CPU signal 10, PC = 0x0
 ....

and now it is impossible to connect via analog modem. ISDN works, still.

After checking the modem, via debug, i saw the Autoselect-Process, 
between the caller and the calle is taken over 100  attempts and then 
giving up.

Does anyone know what to do or where to look for?

Thanks in advance
