Your best bet would be open a support case (see my signature) and send in the following information:
*output to txt file
dm save 1
dm save 2
***offload following to tftp server
supportsave all <tftp-serv-address> /
You could also try proactively upgrading the code if you are hitting a crash. If you give me your model, I can make a recommendation. With that said, the best bet is to open a case and have our engineers look at the information above.
