Description (partial)

ASA reloads when given a file name that is too long. 

This happens when using Smart Care appliance to take a backup of the ASA. This
is due to the mechanism that Smart Care uses to specify the file name. The
Smart Care Appliance simply specifies the source and target protocol in the
copy command, and is then prompted for the rest:

asa# copy startup-config tftp

Address or name of remote host []?

Destination filename []?

The filename is limited to 63 characters, and will be properly truncated, but
then the ASA appends a realm parameter consisting of the interface name (+5
characters), and that causes the filename to exceed the buffer and cause a
checkheaps failure, but only if it is using the last path structure in the
array (there are 8 elements in the array).
