An accounting record has a strict format and clearly an accounting record
was sent to the tacacs daemon that did not meet the requirements, too little
in this case.  assuming its from a network device, rather than a probe from
the internet, the device sending the record has a bug or the packet was
damaged in flight.

junos does not do tacacs account, afaik.  so, the extreme has a bug or a
packet was mangled in flight.  the daemon supports debug options to dump
packets, etc to syslog.
