Hi,

Whenever I try to launch the Cisco SDM on my PC and connect to my Cisco 1721 router running ADVSEC IOS 12.4(17), the router crashes. It's the newest version on the SDM (2.5). I know the SDM worked on it before because that's what I used to configure it originally.

 Here's the crash output on the console port:

validblock_diagnose, code = 12
 
current memory block, bp = 0x82840CC8,
memorypool type is Processor
data check, ptr = 0x82840CF8
 
next memory block, bp = 0x82840E94,
memorypool type is Processor
data check, ptr = 0x82840EC4
 
previous memory block, bp = 0x82840B88,
memorypool type is Processor
data check, ptr = 0x82840BB8
========= Dump bp = 0x82840CC8 ======================

any hardware changed in this router?
'Unexpected exception to CPUvector 700' might be caused by software and hardware problem.

an easier workaround is to use different version of sdm in 1721.

hope it helps.

Tracebacks are caused by IOS bugs.
one more thing that you can try is to change the ios version.

hope it helps.

Any recommendations on which version to change the IOS to? Also, there have been no recent hardware changes... the current hardware was working with other SDM installation before as well.

no particular reason, just one of my clients is using it and never had any problem.
and you can try other version if you have or you can find it easily.

hope it helps.
